He was walking down the hall with Mikey, they were walking calmly while keeping a conversation, nothing out of the ordinary.

-Well, how were the first classes?

-The Biology teacher as on edge as he has always been...

-Yeah, I noticed haha, he has a thing for lecturing you

-I seriously don't understand! It was Kate the one talking and she's on the other side of the classroom! And our voice aren't the tiniest little bit alike!

-Hahaha, well you know Kate...

-A psychopath with homicide tendencies?

-Exactly. Hahahaha

-Were you talking about me boys? - both turned to face the thin lizard with green skin, she was taller than Mikey, but not taller than Donatello. She is a brunette with shiny light blue eyes, she was wearing a sport shirt that said: "Break the rules" and some jeans that were adjusted at the ankles. Her companion was her sister, Susan, a lizard with mustard-colored skin, her hair dyed a deep navy blue, her purple eyes could be mistaken into amethysts; she wore a faded pink blouse and a short white skirt.

-Hey Kate!! - both of the guys smiled at the same time

-Guys, I have told you to not reveal my identity - she winked at them

-Kate! Don't be rude! - her sister repressed her behavior

-Oh come on Sue, I'm just joking!

-Hahaha, it's alright Susy, we don't take it seriously

-Yeah, we know your sister too well

-Hey! But the Bio teacher doesn't! You were saved by luck, lizard

-Hahaha, yeah, not even the cops catch me...

-You are really into your imaginary role as a homicide psychopath aren't you?

-Yes Don, I am

Donnie then whispered to Mikey's ear

-She's actually a little angel - just after his comment, the hit with a knee arrived to his crotch, which caused on him to almost collapse in the middle of the hall.

-And that one was with love, Donnie. Next one you end up in the floor

-Yes Kate... - he whispered, breathless and with his hands on his crotch

With the friendly chat with Kate and her sister over, they both walked away down the wall in direction to the courtyard, where a group of their friends were waiting for them. Meanwhile, Mikey and Donnie sat in the institute's backyard; where skaters used to skate in. Donnie was sitting, still pampering his crotch due to the hit, trying to, only, ease the pain.

-Woah dude she must have hit you hard...

-That girl has a super-mutant strength

-Hahahahaah super-mutant hahahahaha

-You are so childish Mikey...

-You love me just like that

-Hehehe yeah...

With their break finished and the bell ringing, Donnie stood up to go back inside with Mikey, but as he turned he ran into someone and tripped, although the one to blame for his clumsy movement caught him, holding him.

-Uh, sorry I didn't mean...

-Eh, don't worry.. Hehe, it was nothing

Donnie looked at his face then, leather clothing, red bandana, green eyes... It was none other than Raphael Santos, the new one

-My name is Raphael Santos... but you can call me Raph

-Oh, well.. pleased to meet you, I'm Donatello Olester.. Donnie for most of my friends

-Donnie, huh?...Pretty name...almost as pretty as you... -he stroked his cheek as a first movement to his benefit, but Donnie's expression changed to a not so friendly one as he abruptly pulled away from him.

-Look Santos, or Raph, or whatever your name is... I don't know what are you up to with me or what are you doing here or if you bumped into me on purpose, but I don't like the path you are walking down and let me tell you that if you keep walking down that path, you will regret it. Let's go Mikey.

Donatello, followed by a shocked Mikey due to the sudden attitude of his genius friend, entered the institute, while Raphael watched him walk away, face full of amusement and keeping his perverted eyes on how his legs moved when he walked.

-A hard to get guy... I like him.
