You were sitting in the living room when you got a headache, all thanks to Mikey who had thrown a water balloon at you and Raph had gotten mad at him and started to shout at him. It has been going on for more than ten minutes now and it had brought your headache on.

You slowly get up and walk to Donnies lab and look in. "(Y/N) what are you doing in here?" Donnie asks and you look down at your feet.

"W-well I-i have a really bad h-headache and I was wondering if you had anything for it" you say and he smiles.

"Here you go" he says and gives you some tablets before he goes off to tell Mikey and Raph to stop. You take the tablets and start to walk out but you accidentally knocked a vial over and some gas comes out, you fall over and start to feel weird.

"Hey (Y/N) I'm sorry for what I did I didn't know you had a head... woah (Y/N)!" Raph runs over to you and picks you up. "Why are you 4?" He asks and you giggle before poking his cheek.

"Donnie what happened to (Y/N)" Raph shouted and Donnie came running in. "She dropped the sample we got from the kraang. I didn't know what it would do until now" Donnie looks at you. "You have to look after her until I find a cure" Donnie says and Raph groans a bit before taking you to the dojo where he set you down.

"You stay here while I train okay " he says and you nod. He smiles before turning around and he starts to beat up the punching bag. After a while you got bored so you snuck away just as Donnie had found the cure.
"Raph where's (Y/N)?" Donnie asks and Raph runs around trying to find you. Turns out you were with Mikey so you were pretty easy to find.

"Okay drink this (Y/N)" Donnie says and you drink it. A few minutes later you start to turn back to normal.
"I'm back to normal!" You say and kiss Raph passionately. He kisses you back before pulling away when you both need to breathe.

"You were adorable as a kid but not as adorable as you are now" he says making you blush.
