Not exactly excatly like the prompt but still very similar.

Will watched as his boyfriend fought Percy and Jason as they trained. He was deadly adorable. Will was really just there because it's the children of the big three. If a healers not there someone's gonna die. Although something was diffrent with Nico today. Yeah he fought well but not his usual style. He was stumbling a little after doing flips and back spins. His punches seemed less powerful. And his blocks had half effort. But he was still as fast as ever. Even with all of that he could still run away from them. That doesn't mean he hasn't fallen on his face twice, making Percy laugh his ass off as Jason tries not to while helping him up. And whenever any of these were brought up he would pout and throw a hissy fit.

Even though Percy and Jason both thought he was having a bad day Will had something else on his mind. A theory, you could say. You see, the question going through his mind was, could Nico be a litte? He didn't want Nico fighting if he was slipping. But stopping an entire fight and possibly being wrong, plus having a grumpy boyfriend, it wasn't exactly worth it. Will knew of littlespace because of one of his brothers. He had seen him fight while slipping and it was sort of like this. You see Will was his caregiver. So even if his boyfriend was a little he would love him no matter what. And would love taking care of him! But it might not be true and Nico could just be rusty.

Anyways, Nico's and Percy's sword clash as Jason's foot went to sweep him. Nico moved his foot and cut Percy, moving to block Jason as he tried to attack from behind. Suddenly Percy moved in for another attack. Going to strike his arm. Nico's eyes widened as he quickly tried to move away. Suddenly Percy and Jason both went into a a different foot. Making Nico fall to the ground and cut his finger, letting somewhat, a lot, of blood fall out.

"I call out," Nico said fast as he stood up, holding his finger to his chest. Fear and pain in his eyes. Although they clouded with his grumpy and angry look quickly.

"What do you mean you call out?" Percy asked, looking a bit disappointed.

"I mean I'm going back to my cabin," he shrugged, jogging over to his boyfriend. "All checked to go?"

Will checked his arms, face, legs, and stomach before nodding and kissing his finger and putting a bandaid on it, "Only a scratch. It will get better by tonight. You guys should probably calm down if your gonna continue fighting. I don't want you two half dead because your going to fight 1 v 1." Will told Percy and Jason.

"Whattt?? Noooooo. We would never!" Percy laughed as he grabbed a new sword.

"Yeah, we'll only break a few bones!" Jason laughed as he and Percy bump fist.

Will glared at him before turning his attention onto Nico. "I'll come too."

"No, it's fine," Nico shook his head.

"Why not?"

"Just . . . I want some alone time," he smiled slightly before full on running away at top speed.

"That's his version that he needs cuddles and love," Jason joked as he grabbed a new shield.

"Wouldn't you know, Weather Boy," Will rolled his eyes as the two began to fight each other.

As they continued fighting they were way stronger than they were with Nico. It was sort of funny and concerning. Funny that they slacked with Nico. Concerning because there will most likely be something broken by the end unless Will stops it.

Even though it was around seven minutes into the fight Will couldn't shake the thought off about Nico. The littlespace think bugged him slightly but he could let that go. It was more of that he needed space. The hesitant in his voice. What if hes having an anxiety or panic attack in his room? What if its about Tartarus or something in the 30s? They weren't very accepting back then. What if he needed comfort? What if he hurt himself? What if he needed Will?

"Hey Austin!" He called for his brother, who was walking by.

"What's up?" He asked, walking over.

"I need you to make sure these two don't kill each other," Will swatted over to the battling demi gods. "I have something personal to attend to."

"Will try," Austin smiled as they high fived.

Will smiled back and quickly ran over to Nico's cabin. Luckily no one stopped him. And the other two didn't come after him. When he got to the front of the cabin he knocked on the door. He didn't get a response. So he knocked again, a bit louder, just to make sure he heard. He put his ear on the door to hear something. He heard nothing. Nico did go to his cabin, correct? Did he go to Will's? He knocked one more time. He then tried the knob. A little surprised when he realized it was unlocked.

"Hey babe, I'm coming in," he warned, walking into the room and shutting the door behind him.

He gasped slightly at what he saw. Nico was laying on the ground, feet in the air as he looked at him He had a diaper with stars on. Will had seen the diaper before. The stars will disappear if the person who was wearing them wet themself. Nico also had an oversized black skull jacket on. Will's seen it before but hes never seen him in it. There was also a yellow pacifier on the ground. It had a Winnie the Pooh face in the middle. Nico quickly sat up and tried to hide his diaper with his hoodie, tears beginning to run down his face. Will quickly locked the door and rushed over to his boyfriend's side. He pulled him into his arms and rocked the crying baby back and forth until he calmed down a little.

"Hey Buddy it's going to be okay. I'm not mad or upset. Hey, hey, I need you to stop crying. Your too much if a sweet baby to cry. It'll be alright, Honey. I'm here now," Will whispered into his ear. "Such a beautiful baby. Its okay now. I'm here. I'm here. Shhhhh, I won't leave."

"N-N-Not mad?"

"Of course not, Bunny! I could never get mad over this! It's still you. Your still my rock hard Nico," Will then went into a whisper. "You wanna know a secret?" Nico nodded, leaving on his chest. "I'm actually a caregiver. I've had many experiences with littles. Weither it's in the infirmary or my brother. And another little thing, I'd be more than happy to take care of you."

"Weally?" Nico asked as Will dried his tears.

"Of course little one!" Will smiled brightly, bopping his nose. Nico smiled back and looked at his hands. Will looked at where Nico was staring and saw his finger. The one he cut earlier. "Does it hurt?"

"Nu," Nico shook his head.

"Well how about we take off that big kid bandaid and put a Disney one on?" Nico looked up at Will with sparkling eyes. Will chuckled and slowly took of Nico's current bandaid. Blood started falling immanently which made Nico start whimpering and squirming. Will dried the blood and put on Cinderella bandaid. Nico smiled and went back onto cuddling Will's chest.

Well that's something different from big Nico. Big Nico isn't the biggest on affection. He loves cuddling, yeah, but at night. And when cuddling stops he doesn't immanently go back to it. Plus, he usually flinches when Will tries to first make contact. Little Nico seemed to love the affection. It was adorable and koala like almost.

"Such a cute little baby," Will cooed as he picked up the paci and stood up, Nico on his hip. "How about we wash this real quickly and watch some shows? Does that sound good?"

Nico made an exited giggle as they traveled to his bathroom. Will made heist to wash the paci and dry it before placing it into Nico's mouth. Nico cooed and placed his head on Will's shoulder. Will went back to the bunk area and sat on the bed with Nico. He saw a cute Cerberus plush and handed it to Nico, who snuggled it with a tight grip. Will placed Nico between his legs and layed his head on his chest. He grabbed a remote for the TV, Leo had made them for all cabins. There was always war for the TV, unless your Nico, which is why Will comes over so much.

"Whatcha wanna watch, Baby?" Will asked as he scrolled through the channels.

Nico whined in response, feeling a bit to small for words right now. Will understood and slowly went through the channels. Stopping when Nico made grabby hands at Ruby Gloom. They stayed like this for hours. It was amazing.
