It's been a month since I met the male turtles. Raph continues to visit to use the gym and I've gotten used to his presence. He's even basically made that room I let him stay in his. I'm actually beginning to enjoy his company. Finny enjoys him too. I've been teaching him different martial arts moves and in return, he teaches me how to use his sais along with a few of his own martial arts techniques. We've become close so much so that we're like new best friends, but with dark, hidden secrets from each other.

...Raph's POV...

(I'm in the mood to pummel something... This dummy is not going to do. I'm going to Mysteria's place!) I look at my two brothers who're sitting around the couch with me watching tv, Donnie cooped up in his lab. (Gotta make an excuse...)

"Hey, guys? Casey just texted me asking if I wanted ta hang out, so I'm gonna go. See ya later!" I say, grabbing my sais and make my way towards the exit.

"Hold up," Leo calls out.

I sigh. "What?"

"You've been hanging out with Casey a lot lately, any reason?"

"Yeah, he's my buddy. It lets me get away from you," I huff. "See ya!"

"Wait."

"What now?!" I complain.

"Just reminding you to be careful. Mysteria is still out there and we still aren't certain if she's a threat or not. If she's strong enough to defeat Karai in a few seconds then she's definitely strong enough to beat you," Leo says.

"I understand that. Besides, I'll be with Casey."

"I know that's what worries me," Leo says. "Have fun."

"See ya, mom," I sarcastically reply and dash off through the sewers to the city. I travel to the abandoned New York streets and enter Mysteria's place after making sure no one is looking. "I'm back!"

Mysteria comes around the corner and looks at me with a sigh. "Wanna come spar with me?"

"Hell yeah!"

We take our fighting stance and begin.

...Leo's POV...

I watch Raph leave then pull out my T-phone and call up Casey.

"Yo," he answers.

"Did you just text Raph to come over?" I ask.

"Yes..."

"Casey?"

"Fine! No, I didn't!" he whines.

"Then, why say yes?"

"Because Raph told me to if you asked that question and I didn't really ask," he answers.

"Hey Leo, who you talking to?" Mikey asks.

"Casey."

"Let me talk to him!" Mikey says and leaps over the couch, putting his head on the other side of the phone.

I roll my eyes. "Why?" I ask.

"My guess is that he has a lady friend! Hooo!"

"Raph? Really?"

"Raph has a lady friend?!" Mikey squeals and runs off towards Donnie's lab. "Donnie guess what?!"

I hear a crash come from the room and turn my attention back to Casey.

"Really?" I ask.

"Naw, probs not, but he never told me why. He threatened to break my hockey stick if I didn't."

"Of course he did," I scoff and roll my eyes. "Do you know where he is?"

"No clue."

"Do you think he's with April?"

"Naw, April's with me at the arcade right now."

"Alright, thanks for the help," I say and hang up. I walk over to Donnie's lab.

"Is it true?" Donnie asks, once I enter the room.

"I don't know about lady friend, but it sure isn't Casey he's hanging out with," I say. "I need you to track his T-phone."

"What if he's not hanging out with anyone?" Mikey asks.

"Then we won't have to worry as much," I answer.

"I got him!" Donnie exclaims. "He's at the abandoned part of the city near where Casey lives."

"Then let's go," I say and the three of us quickly exit the lair.

We exit through the usual sewer cap into the night.

"I wonder if he's hanging with Spike?" Mikey questions.

"Doubtful," Donnie replies. "They didn't exactly end on good terms."

"They could've made up?"

"Why isn't he telling us the truth?" I wonder out loud.

Mikey gasps. "What if he's a traitor and joined Shredder's side?!"

"Mikey!" Donnie shouts and smacks the back of his head. "I doubt Raph would do that! He's our brother he'd never do something so shameful!"

"Owww..."

"Donnie's right Mikey. Raph wouldn't do something like that unless he was under some kind of mind control," I confirm.

"It was just a thought... You didn't have to go all Raph on me, Donnie..." Mikey whines and holds his head in pain.

"You shouldn't be thinking stuff like that though," I say.

"Jeez, sorry!" Mikey whines as we leap across more buildings.

After about 10 minutes we arrive at our destination.

"We're here!" Donnie says.

"This building?" I ask.

"The radar says he's right below us."

"Then let's go check it out," Mikey says and enters the building first.

"Mikey..." I grumble then quickly follow after him.

The three of us sneak along the rafters and jump down after discovering nothing.

"It says that he's right here!" Donnie complains. "But he's not here!"

"Sewers?" Mikey suggests.

"Guys, this used to be an old military secret base. That's according to old records about this location at least," Donnie says, looking at records on the T-phone.

"How do we get in? It must be heavily guarded," I say.

"What is Raph even doing in there?" Mikey asks.

"Don't know and I can hack the system just give me a second," Donnie says then opens the electrical box and starts fiddling with the cables.

"Donnie, hurry up," I complain after 5 minutes.

"I don't know how to hack this. This technology blocks me from even trying to put in a hacking system. Whoever made this is incredibly smart," Donnie says impressed.

"This is not the time to be impressed. We need to find a way inside," I say.

"This is an old military base. That means that it has many entrances if they needed to escape," Donnie explains.

"Then let's split up and find one," I say.

...Liz's POV...

"Is that really the best you've got? Now I see why Shredder beat you," I comment.

Raph growls and lunges at me. I grab his face and flip him onto the floor. I lean in front of his face with a smirk.

"Wipe the smirk off your face before I do it for you," he growls.

"Please, enlighten me on how you're going to do that," I smirk.

"I'm going to..." he growls.

"I pinned you down. Good luck wi–" I begin, but am cut off by the alarm I set up. "Somebody's here." I stand and help Raph up. "Somebody's trying to hack their way in." I get over to the computer and pull up the camera. "Look who's here for you."

"My brothers," he sighs.

"Your brothers have become quite nosy in your personal time," I comment.

"That's the thing, we don't have any personal time."

"Bummer," I say. "Anyway, we need to get rid of your brothers."

"Agreed."

"I have the whole place booby trapped and enacted when somebody tries to fiddle with my stuff," I announce and sit in front of my screens that show everything happening outside. "Wanna play 'mess with your brothers'?"

"Hell yeah!" he cheers.

"Then get on the computer next to me and let's play," I giggle.

"As long as we don't hurt them."

"Of course not."

"Then let's start!" he yells and aims his laser.

We listen to Leo yelling at Raph and chuckle.

"They must be tracking your T-phone," I say.

"Oh, crap! I forgot about that!"

"Tell you what, leave it here and tell your brothers that the Kraang must've gotten a hold of it in one of your battles. I'll get rid of it for you. That or we could destroy it right now," I suggest.

"I like the Kraang idea better, that way you can lead them away from here."

"Aww, I wanted to destroy it."

...Leo's POV...

"Uh, Donnie?" Mikey asks. "Are military bases loaded with weapons?"

"Abandoned ones are likely to not have any," he replies.

"Then why are there lasers shooting at us?!" Mikey yells and dodges a beam.

"Raph! You better not be doing this!" I yell. "You're so dead if it is!"

"I don't think Raph would shoot lasers at us!" Donnie yells.

"Unless he's working undercover as a Foot solider!" Mikey yells.

"Mikey!" Donnie and I yell.

"What? You never know."

"We need to retreat," I say. "We'll come back some other time."

...Liz's POV...

Raph and I high three. "Whoo!"

"That was actually entertaining," Raph says.

"Yeah, let's eat some ice cream or something to celebrate our victory."

"Sounds good."

We leave the monitors and make our way to the kitchen.

"Meh!"

"You hungry too?" I ask Finny. He nods and I take out a lettuce ball from the fridge then give it to him. "Here ya go little buddy. Raph, I finally got ya your favorite ice cream like you said."

"Yes!" he cheers.

We sit down at the table and dig into our ice creams, not even bothering to put it in a bowl.

"Mmm."

"Hey, don't you, like, get lonely being down here all by yourself?" Raph asks. "Well, before Finny."

"Sometimes, but I like being alone. It means nobody can bug me and I can train without any annoyances."

"I get what ya mean. That's why I like coming here because you don't bother me."

I laugh. "Are you finally confessing your love for me?" I tease.

"What?! N-no! Don't put words in my mouth!"

"Anyway, let me see that T-phone of yours," I say and hold my hand out. He places it in my palm and I take it apart to look inside.

"Whaddya doing?"

"Tweaking with it." After fiddling with things and removing things, I put it back together. "There. No more tracking device to bother us. I switched it off and can turn it back on if needed. This is my phone now, so you can call me whenever you might need help. Next time you come we can get each other's contact info."

"Cool, but I guess I should be going before I get bitched at more by my brothers when I return," he says, places what's left of his ice cream back in the freezer, washes off the spoon, and gets his stuff together. "See ya later, Mysteria."

"Bye, Raphy."

Here's a quick little filler chapter.
