In the end it was Logic who realised and explained it all to them. In fact, by that point he was berating himself because it should have been obvious! Really, it was the only logical answer to Prince and Anxiety's behaviour.

It more or less started when Logic was having a conversation with Compliment a while ago. Compliment had brung something up concerning Prince and Anxiety, how they had been acting a bit oddly. He mentioned something about them watching Disney movies together and apologising after any argument. Logic hadn't even noticed, but ever since then he had kept an eye out, and he found that statement to be true.

He saw that sure enough, in a relatively small period of time after an argument, one or the other, Prince or Anxiety, would seek out the other and apologise. Sometimes it was something small, just a simple I'm sorry. Other times it was more than that, perhaps a gesture or an action. Watching Disney movies together seemed to be a preferred peace offering, and sometimes they built pillow forts together, or made each other hot chocolate. Seriously, how had Logic not noticed?

But all Logic had supposed was that they had decided too try to be civil, perhaps even tentative friends. Perhaps Thomas had convinced them, like he had tried to convince Logic and Morality to work together. Perhaps it was just because they realised were all living in the same mind, and that holding grudges wasn't very fun when you saw each other every day. In fact, in everyone else's' opinion Anxiety and Prince's constant arguing had become tiresome. Logic hopes that this way they could all have civil conversations.

* * *

Logic started noticing more little things when Dad brought the pair up while they were hanging out in Morality's room.

"Hey Logic, did you know I've been seeing Princey and Anxi hanging out quite a bit lately?" Dad mentioned, as he hung upside down off the bed. Logic looked up from his book curiously, eyebrows raised.

"Really? Tell me more." He demanded.

What could Logic say, as much as he would deny it he loved gossip. Dad accidently slid off the bed, hit his head on the carpet, then popped back up and plonked down next to Logic, grinning with a sparkle in his eye.

"Well, the first time I actually took notice was when I told Prince to do his job, because Anxiety was the only one with Thomas at that moment. Anxiety had been doing that a lot the last few days I'd noticed, so I told Prince to get him to back off. Honestly, I'd been expecting Prince to try to send Anxiety to," Dad shuddered momentarily. "To send him to Lilly." He whispered, and Logic grimaced.

Lilly was the biggest, baddest, meanest part of the mind. Towards anything that threatened Thomas, of course. According to him she was actually a sweetheart, just very protective. In fact it was believed that Lilly embodied the defensive side of Thomas, but nobody knew where to find her until she was either summoned or they were sent to her. Anxiety was the only person to have ever been sent to Lilly, but even before that there had been horror stories about her. There was also a rumour that she floated through many other people's minds, helping them out and protecting them when they needed her. She wasn't restricted to Thomas like they were, and so she had a form all of her own. Scary.

Logic shook himself back to reality.

"Did it work? Was Anxiety sent to her?" He hissed, looking wide eyed at Dad, who stared just as intensely back, but shook his head.

"Nah. I teleported in a while later because there was a cute dog outside that I wanted Thomas to pat, but Prince and Anxiety were both still there!" Dad was making this sound much more dramatic than it probably was, but Logic didn't really mind. It was Dad, after all, what else did he expect?

"Go on." Logic urged. Dad lit up.

"Okay! So anyway, they weren't even fighting! They were just standing there, smiling! Even Anxiety was smiling, and Thomas looked like he was enjoying himself. Of course when I arrived they covered it up, you know how they are, always trying to look tough." Dad smiled fondly.

"Kids these days. But they were totally getting along!" Dad sighed happily.

"Finally. I just want everyone to be friends, that would be so nice. And we could have barbecues together and watch a football game, and g-" Logic cut him off.

"Right. So they're getting along? Huh. I noticed that too, and so has Compliment. That's the majority of us, so the data can't exactly be wrong. Prince and Anxiety have become closer, and friendlier. I wonder why that is?" Logic questioned himself, shutting the book softly and leaning back against the headboard and letting himself run it through his mind. He couldn't recall anything major happening, at least that he knew of. Perhaps they had both mutually agreed to try to get along better?

Suddenly Dad got up and stretched, pulling his shirt back down when it rode up and adjusting his glasses.

"Yeah, well, one of the kids wants to go to the park now. I gotta take her." Logic raised his eyebrows, but at that moment Dad's daughter flashed in and grabbed his hand.

"Take me to the park!" She demanded. Dad crossed his arms.

"What do you say?" He questioned sternly. The girl dropped visibly.

"Please?" She asked hopefully. Dad broke out his blinding grin.

"Alright! Let's go!" Dad smiled at Logic one last time, quickly said goodbye, and then they disappeared, leaving Logic to his book and thoughts.

* * *

The third time Logic realised something was up was when Pranks decided to play a prank on Anxiety. Logic couldn't fathom why Pranks thought that was a good idea; who knew what would happen? Nobody knew how Anxiety would react. So he spent the next few hours mulling over it, running scenarios through his head and trying to find the most logical way Anxiety would react, but he kept coming up blank. He just didn't know Anxiety well enough, he didn't have enough information! It was maddening. Finally, about a day or two later, Pranks was setting up a prank in Logic's room when he walked in.

Logic just stood in the doorway for a few minutes, arms crossed and eyebrows raised, but Pranks didn't notice him. He was too busy hanging up a string of fairy lights on the wall. Eventually Logic cleared his throat, loudly. Pranks looked over to him and flinched in shock, trying to step away, but he was standing on a step ladder. So Pranks toppled backwards, still holding onto the fairy lights and crashed to the ground, quickly becoming entangled in the wires and tiny light bulbs. Logic just sighed.

Pranks lay groaning on the white carpet for a few seconds before Logic made his way over. He nudged Pranks with his foot.

"Wounded! I've been mortally wounded! Logic- please, tell Thomas... tell Thomas I loved him. And remember me as I was, not as I am. Please ignore the fairy lights. I- I can see the light! I'm fading..." Pranks moaned in agony one last time, before his eyes slid shut and his head thumped back onto the carpet, mouth open and tongue out a little bit. Logic rolled his eyes.

"Pranks, get up." He said.

"Shh, I'm dead! Dead, Logic! I've died! I'm dying! Now I'm d-" Pranks muttered out of the corner of his mouth, eyes still shut, before cutting himself off dramatically. Logic quickly ran the situation through his mind and decided the quickest way to get Pranks to leave was to play along.

"Oh no. Pranks has died. What a terrible shame. I shall miss him dearly. What on earth will I do now? How will I cope? Oh no." Logic said robotically, but it was enough to make Pranks grin and open his eyes. He sat up straight, trying and failing to untangle himself from the lights, before ignoring them and smiling brightly at Logic.

"Surprise! It was just a prank, I didn't really die!"

"Oh, yay, that's good. Could you please leave now?"

"Do I have to? We never hang out." Pranks pouted. Logic rolled his eyes.

"Why would you want to hang out with me? We're practically opposites."

"We are not! You just use big words a lot. I can do that to! I'm actually very... eloquent!" Prank seemed quite proud of himself, and Logic d̶i̶d̶n̶'̶t̶ ̶h̶a̶v̶e̶ ̶t̶h̶e̶ ̶h̶e̶a̶r̶t̶ couldn't be bothered trying to force him out of his room.

"Fine. You can stay, but I'm just going to be reading my book." Logic warned.

"That's fine!" Pranks said happily, so Logic got up and wandered to his bed, summoning Harry Potter and the Prisoner of Azkaban and opening it up.

Logic leafed his way through the first few chapters before Pranks managed to disentangle himself from the lights and bounce his way over to the bed. Sitting down close to Logic, he titled his head and read the title.

"Ooh! Harry Potter, I love Harry Potter!" He exclaimed excitedly. Logic hummed absently and Pranks sighed.

"You know, I'm in your room for 5 minutes and you walk in and catch me setting up a prank, but I was by Anxiety's room for hours and he didn't even catch me. I had to go find him!" Logic looked up and placed his book down, adjusting his glasses.

"Oh really? Where was Anxiety?" He asked curiously.

"In Prince's room."

"Really? Why?"

"I don't know." Pranks shrugged. "I guess they were just hanging out, which is kind of weird but whatever. Anxiety was totally ungrateful for me cleaning his entire room afterwards, he didn't even go back in! He just stayed in Prince's room and slept there or something." Pranks grouched. Logic raised his eyebrows; he seemed to be doing that a lot lately.

"Really? And they were both just... okay with that?"

"Yeah, I mean I guess. Prince didn't seem too agitated. Anxiety didn't even seem to care that much that I pranked him." Logic narrowed his eyes in thought. Something was definitely going on; they went from mortal enemies to sleeping over in each others rooms? Anxiety didn't even care that he'd been pranked, he just went back to Prince? Something had happened. Something had changed, obviously. And the most infuriating thing was that there was an idea at the back of Logic's mind, it was the answer, but he couldn't quite reach it! He couldn't piece it all together, but to go straight from enemies to best friends meant something. They'd obviously talked about something, and perhaps friendship had been the resolution but... that wasn't quite right. There was something else. And Logic didn't know what it was!

"-w it is. I don't know. But I mean, them getting along is probably a good thing. I should be going though. Thanks for hanging out with me, Logic, but I'm gonna go hang out with Compliment now. Bye!" Logic realised he'd completely zoned out and missed what Pranks was saying, but he didn't seem to have noticed. With that Pranks sprung up, bouncing from the room with the fairy lights wrapped around his arm. And so Logic was left alone with the puzzle of Prince and Anxiety lingering on his mind.

* * *

The answer came only a few days later. Logic was drawn out of his room by shrieking and the thudding of footsteps. Frowning, he stalled out into the hallway and looked around for the culprits. There were him in sight, but he's heard them run past his room multiple times. So he listened instead.

Sure enough, but a moment later, there was another holler from the direction of the living room, which Logic immediately made his way towards. When he got there, though, what he saw stopped him in his tracks.

Prince and Anxiety were lying on the couch together. Or, more accurately, they were wrestling on the couch.

"Anxiety! I demand that you hand me that phone over this instant! Those photos are horrible! Oh, the indignity!" Prince wailed. Anxiety kicked his legs and tried to wriggle away, holding his arm outstretched, the phone clutched tightly in his fingers.

"No! You- ow! You can't demand anything, Pretty Boy! It's my phone, you shouldn't have fallen asleep! Of course I was going to take photos! It's your own fault! Pr- Hey, ouch! Prince, stop!" Logic noted how Prince blushed when Anxiety called him Pretty Boy. Then Anxiety freed his other arm and poked Prince between the ribs. Prince suddenly grew very still, and narrowed his eyes. Logic sensed danger.

"Oh, that's how you want to play, Anxiety? Alright then." Anxiety then froze, and somehow grew paler.

"Oh no." Logic heard him whisper.

Then Anxiety had rolled off the couch and out of Prince's arms, and was pelting away as fast as he could run. Prince immediately gave chase. Logic stared after them, completely puzzled, until there was a loud thud.

"Did you just tackle me?" Anxiety's incredulous voice drifted to Logic.

"Yes." And then Anxiety was shrieking with- laughter? What on earth? Logic had never even seen Anxiety smile!

"S-stop! Princey n-no! I'm sor-sorry! Sto-o-p! Stop t-tickling m-me!" Logic could hear Anxiety gasping for breath between rounds of giggles.

"Never!" Prince's gleeful voice shouted back. Logic was stunned. What? Anxiety was laughing? He was happy? Prince was tickling him? And happy? They were playing? Together? And- wait. What photos?

He really was too curious for his own good. Snooping through other people's possessions was an incredible breach of privacy. Logic knew this. But Anxiety had just dropped the phone on the couch when he escaped, and it was lying face up on the cushions, calling out to Logic, telling him to just take a little peak. Logic narrowed his eyes at the phone like it was offending him, and he tried to resist. He really did. But it would only take a few steps, and the light glinting off the screen made it look so inviting to pick up.

He only lasted a minute. Looking around, Logic made sure Prince and Anxiety were still fighting in the hallway.

"P- Pretty boy, I s-swear if you do n-not get off me RIGHT NOW you'll r-regret it!" Anxiety tried to sound angry, but it was interrupted by giggles.

"You started this, Kitten." Logic could hear the wicked grin on Prince's face. There was a pause.

"... Kitten? What? Why Kitten?"

"Because you get so angry and defensive but you just look so cute!" Prince cooed.

"I'm not cute!"

"Yes you are, you're adorable!"

"You know what-" There was a scuffling noise, then Prince started laughing uncontrollably.

"No-o! I m-mean, I'm not e-even tick-ticklish there!" He shouted down the hall. Assured that they weren't coming back any time soon, Logic dashed forward and snatched up the phone. Morality would be so disappointed.

Logic tried to think through the noise in the hallway. There was a password, of course there was a password! He'd tried 12345. He'd tried typing out Anxiety with the keypad. He'd tried everything and already locked himself out. He still had to wait 11 seconds until he could try again.

"Haha! Defeated!" Prince's victorious voice floated towards Logic.

9

"No. I'm. Not!"

8

"I challenge you to a duel!"

7

"Haha, no thanks Princey."

6

"Why? Are you afraid?" Prince teased.

5

"Of hurting your little feelings when I beat you." Anxiety snorted.

4

"Oh, you do care."

3

"..."

2

"..."

1

"... Of course I care, Prince. But not enough to NOT TICKLE YOU!" Then more shrieks of laughter.

Honestly, it was kind of disconcerting; nobody ever really played around in the mind much. It was a rare occurrence. But also kind of... nice. To hear them happy. Almost. Logic replayed the last line in his head, and... Aha! Logic turned his attention back to the phone and quickly typed in PRINCE by looking at what number the letters were under. 774633. Immediately the phone unlocked, and Logic saw the Gallery app was open.

Perfect.

Logic swiftly tapped on the first photo, but when he saw what it was of he had to take his glasses off and clean them to make sure he was seeing properly. He was.

It was a photo of Prince and Anxiety. But Prince was obviously asleep. His eyes were shut tight and his mouth was slightly open. His hair was messy and swooped into his eyes in a way Prince would never allow whilst he was conscious. He was all cuddled up into a pillow on a bed, knees curled up and face half pressed into it. Logic wasn't sure if he was imagining the tiny trail of drool. Anxiety was hovering over Prince, grinning wickedly as he took the selfie, a mischievous glint in his eye. When had they been together? Why had Anxiety been in Prince's room while he was sleeping? What was happening? Logic had to know. So he swiped to the next photo.

This one had Anxiety poking his tongue out at the royal boy, who was still in the same position. Logic briefly wondered if this was the night Pranks said Anxiety had stayed in Prince's room? He went to the next picture. This time Anxiety was lying down with his head on Prince's chest, the soft duvet pulled up around them. Prince had an arm flung across Anxiety's stomach and Anxiety was rolling his eyes in the selfie. Logic was beginning to piece things together, a theory was brewing in his mind. But- it was impossible. Surely not! They were complete opposites, there was no way. They might just be... really... good friends? Yikes, that sounded weak even in Logic's mind. Next photo, please.

The next photo was the last, and it kind of solidified Logic's theory. Anxiety and Prince were full on cuddling in it. And Anxiety had his next stretched up to where he was lightly kissing Prince's cheek. Prince was still asleep, his hair still messy and his mouth still open, but his arms were wrapped around Anxiety and he was curled in close to his side. It was actually kind of adorable. Logic swiped again but that was the last one of Prince and Anxiety together. So Logic sighed and put the phone to sleep, placing it back on the couch.

Prince and Anxiety. Anxiety and Prince. Together. Possibly. Maybe. That was the theory, and it made all the strange behaviour suddenly make perfect sense. But they were opposites! Could it even be possible? That they had liked each other all along? But they argued so often. But they were also so weirdly cute together. Logic deduced he had to ask them, it was the only way to find out if he was right or not.

And then Logic became aware of the silence.

The silence seemed to ring through the mind, reverberating off every surface as it attacked Logic. Silence. No laughing. No giggling. No shouts of triumph. No pleads to stop, no threats, nothing. Just a heavy hanging silence. He'd been so wrapped up in his thoughts that he hadn't even realised that Prince and Anxiety had stopped making noise. And suddenly Logic knew that they were there. He could feel them watching them, and he cringed to himself. That was embarrassing, he'd been caught snooping!

Ever so slowly Logic raised his head, and immediately made eye contact with the two across the room. Anxiety and Prince were staring at him wide-eyed in the doorway. Slowly Anxiety looked to the phone, then back to Logic, and raised a single eyebrow. Logic blushed. Then he realised that Prince and Anxiety were standing close together, almost shoulder to shoulder, and their hands were linked loosely, like it was just an unconscious action. Maybe it was.

Suddenly Prince wailed a despairing sound. "Noooo!" He cried dramatically. "You saw the pictures! Oh, the shame." He despaired. Logic frowned and Anxiety sighed.

"I need to change my pin." Is all he grumbled. He tugged on Prince's hand. "Get up, Pretty Boy. Stop being so dramatic." Prince wailed in response, and Anxiety turned to Logic for help.

"Oh. Uh, you look... fine, Prince." Logic assured awkwardly. Prince blinked.

"I do?"

"Of course you do, you're a pretty boy no matter what. Can you stand up now?" Anxiety rolled his eyes. Prince beamed and jumped up.

"Thanks, Kitten!" He smiled. Anxiety scowled at him, but reached out to hold Prince's hand anyway. Then he returned his attention to Logic.

"Why were you looking at the pictures, anyway?" He asked.

"I, uh, I had to... collect information. About my theory. To see if it was correct." Logic stammered.

"Oh, and was it? Did you succeed?" Prince asked cheerfully.

"Well, that's yet to be determined. I'm going to ask you personally now though, because it's the only way to be certain." The pair nodded at him, so Logic plowed on ahead.

"Are you two dating?"
