Leonardo
"Y/n, you're not going on missions, and that's final!" Leo says, raising his voice a tad. You frown and march up to stand in front of him.

"Why? So I can sit around the Lair, missing out on the action? I want to be out there with you, fighting bad guys!" You stare straight at Leo.

"No, I would rather you be bored then be put in harm's way." He crosses his arms and glares at you.

"Leo, why are you acting like this? What's wrong with me fighting alongside you? Your being a real jerk!" You shout at him, making him flinch. You storm out, not bothering to wipe the tears that ran down your cheeks. You run to your shared room and slam the door shut, leaving Leo in the dojo.
Leo throws his arms in the air and goes to meditate.

"Leonardo!" Master Splinter calls from his room. Leo gulps and walks in.

"Yes, Master Splinter?"

"I heard of your argument with Y/n. Do you wish to talk?" Leo nods and sits across from his father. "When you're ready, my son."

Leo sighs. "I overheard Y/n talking with Raph, saying something about going topside with us, and I confronted her, told her that I don't want her to. She asked why and I told her because I said so. Then she got upset and we started yelling, she called me a jerk and stormed off." Master Splinter nods. "I don't know why I did it, I just, I don't want her to get hurt." Leo holds his face in his hands and sighs. Master Splinter pats his shell.

"There there, my son. Being in a relationship is difficult, but I believe you and Y/n were meant for each other. Go to her." Leo nods and bows quickly before running to you.

He opens the door silently and sees you laying on your side awake, staring off into space. He immediately regrets shouting at you, seeing your red eyes. He walks over and lies beside you, pulling you close.

"I'm so sorry Y/n. I didn't mean to tell at you. I was worried. I don't want you to get hurt, I was scared." He whispers, and let's a few tears fall. You turn to face him, and wipe away his tears.

"Please forgive me Sugar." He says, resting his forehead on yours.

"I forgive you, Babe. I'm sorry for shouting too. I didn't mean it when I said your a jerk. Your perfect. And I love you." Leo smiles and strokes your cheek before kissing you lovingly.

"I love you too Y/n, but seriously, you're not going on missions."

You sighed and nodded, "fine."

Donnatello
You and Donnie were doing experiments in the Lab when something blew up in your face. You were fine, but Donnie was freaking out.
You were currently sitting on the kitchen counter while Donnie treated the small cut on your arm.

"Donnie, I'm fine, you can stop worrying." You say as he puts a bandaid on your cut. "C'mon, let's go experiment again." You smile and jump off the counter when he grabs your hand.

"Y/n.. I- I don't want you to be in the Lab anymore.. for your safety."

Your eyes widen as you pull your hand from his.
"Why would you say that?" You say, "it's just a cut. Why can't I be in the Lab with you?" You say, your voice cracking slightly from the tears bubbling up. You swallow the lump in your throat as your sadness boils to anger, and you let a few tears slip away as you frown at Donnie.

"I just want you to be safe, that's all. Please understand, I just want to protect you."

"Oh I understand. I'll just sit around and do nothing, like a good girlfriend, cause that's what you want." You snap, and storm off. Donnie tries to call after you but you ignore him and run to your destination.

"Oh what have I done." Donnie mutters in his hands.

"Hey Don," Mikey peeks around the corner, "Leo wants you."

"I'll be right there." Donnie mumbles, and splashes cold water on his face, then dries off.

"Yeah Leo?" Donnie says, entering the dojo, "you called?"

"Hey Don," Leo starts, standing from his sitting position, "I heard you and Y/n screaming at each other, you ok?"

"Oh, that, yeah." Donnie rubs his arm, looking down shamefully. "We had a fight. I asked her to stay away from the Lab, for her own safety. She was offended, and said some things, then ran off. I was only trying to protect her!"

"Well, try to see it in her perspective. If someone did this to you, how would you feel?"

"Upset, like they were pushing me away.. oh, I need to go find her! Thanks Leo!"

Donnie searches for you, wearing the humanizing watch just in case. He finally finds you at the coffee shop, staring sadly out the window. He walks in, human form, and sits across from you.

"Y/n? I'm so sorry Baby Doll, I was stupid, your the best Lab partner I could ever wish for. Your smart, talented, beautiful.. I was just worried, I don't want anything to happen to you. Will you forgive me, please?"

He holds your hands over the table, and you look at him. Your eyes are still a little red from crying, and it hurt Donnie to see that he did that to you.

"Yeah, I forgive you Handsome. I might have overreacted. I'm sorry too." Donnie smiles wide and rubs the top of your hands with his thumbs. You both stand and leave the shop. Outside, Donnie gives you a sweet, loving kiss.

"I love you Baby Doll." He whispers to you.

"I love you too Handsome."

Raphael
"I don't want you talking to him."

"Raph, you can't tell me who not to talk to!"

"Yes I can!"

"No you can't!"

"YES!"

"NO!"

"YES AND THAT'S FINAL!" Raph roars at you, stepping closer with each shout. You step back and glare at him. Raph found you talking to Casey, and dragged you to his room, now here you were.

"I am my own person, and I will talk to whomever I please!" You shout back, stepping forward and jabbing his plastron with your index finger.

"Y/n so help me.." he trailed off, stepping closer until your back hit the wall and he was mere inches from you. He panted, his warm breath hitting your face and making you squint. Raph growled and you frowned.

"Now what?" You ask, cocking an eyebrow.

"It's so hard to stay mad at you, you just make it impossible."

You smirk and Raph smiles lightly at you.

"I'll let you talk to Casey, but if he tries ANYTHING, I'll beat him to a pulp. Got it?"

"Yeah, I got it," you sigh, "he isn't even that interesting anyway."

Raph smirks, "that's my girl."

You smile and place a small kiss on his lips, then pull away quickly. Raph growls and pulls you close by the waist, kissing you roughly.

"I love you Sweetheart." He murmurs against your lips.

"I love you too Hot Stuff." You reply.

Michelangelo
"Whoa!" Mikey jumps back from your side kick, and smiles wide. "Great side kick Y/n, but drop your stance a little." You nod and do so, waiting for Mikey to attack.
He lunges forward and sweeps your feet, making you fall, then rolls you over and puts you in a choke hold. After a few seconds you tap out and he lets go.
"Wow, you're doing great Gumdrop, soon you'll be taking down Leo!" You giggle and kiss his cheek.

"Thanks Gummy Bear. Can we take a break?" He nods and sweeps you up, taking you to the couch for cuddles. He switches on your favorite show when you start to argue.

"No, (least favorite character) is just misunderstood!"

"Mikey! (Least favorite character) (evil thing they did)! You can't say 'he/she's misunderstood'!"

"Yes I can!" He huffs and crosses his arms. You do the same and move to the other side of the couch.

After a few minutes of silence Mikey looks at your figure, facing away from him. He scoots to you and hugs you, making you jump a little.

"I'm sorry!" He says, nuzzling his face in your hair. "Please forgive me!"

You giggle and turn around to face him. "I forgive you, you big baby." He smiles and cups your face, giving you a sweet kiss.
