Leo
"You have to promise to call every night, alright? I don't think I can go that long without seeing your face." Leo said anxiously, pulling your suitcases out of the luggage rail at the airport.
"And text me every hour, and FaceTime's on days that you don't have class. That way I know that nobody bad will sneak up on you or anything."
"Leo," You said, swinging a backpack up onto your shoulders. "I'll be fine. I'll call you everyday, alright? And you're better than any other guy that'll be there."
"FLIGHT 320 BOARDING NOW." You glanced over at Leo, to see him looking very tense, and gently took his hand in your own. Leo seemed to realize that this was it, you were really leaving, and he wouldn't see you for a long time.
"I love you, Y/n." Leo said, pulling you into a bone-crushing kiss.
"I love you too." You said softly, kissing his cheek once more. Then you picked your suitcase up, and boarded the plane.

Raph
It was very unlike Raph to be quiet and polite, yet you couldn't help but wonder if going to college is what made him change so suddenly. He grabbed your suitcase off the luggage claim rack, and wheeled it along the terminal while you ran through security clearance one last time.
"FLIGHT 501 BOARDING NOW."
So perhaps that's why you weren't surprised when Raph swept you up into a bone-crushing hug, and simply held you for a few seconds.
"I'm going to miss you Y/n. A lot." Raph murmured, kissing the top of your head.
"Of course you will," You snorted. "Who won't miss me?" But one glance at Raph's face, and you knew he wasn't having it.
"I love you Raphie, don't worry." You said gently, kissing him softly.
"I love you too Y/n. And I always worry about you." He said, his voice cracking a little. And with a little wave and a sad smile, you boarded your plane.

Donnie
You knew Donnie got quiet when he was upset, but it still broke your heart that going away to college was what was making him upset. He helped you with your bags and pointed you in the right direction for your terminal, all with a sad frown on his face.
"FLIGHT 372 BOARDING NOW." You took your bags from Donnie and kissed him hard, to see if it would make him start talking again.
"I'm going to miss you Donnie." You said quietly, noticing that his eyes were a little brighter than they had been before.
"I'm going to miss you too Y/n." Donnie said. "But guess what? When you go to college, I'm going to be getting my degree online as well!"
"That's great!" You said enthusiastically, kissing him again.
"Yeah," Donnie said. "I love you Y/n."
"I love you too." You said, before picking up your bags and boarding the plane.

Mikey
"Y/n, look! What is that? Is that a plane? Woah, that's so cool! Why haven't you taken me here before?" Mikey was bouncing off the walls, figuratively speaking. You had no idea that he would be this excited to be in an airport.
"Mikey, love, calm down so people don't stare." You giggled. He quieted but was still bouncing as he helped you pulled your bags off the luggage rack. You took them from him gently, and then gave up when Mikey started asking tons of questions again.
"So do your ears start popping really fast? Any laser cannons? Are you going to sit by the window?"
"Mikey!" You laughed, but covering his mouth anyways. "There's no laser cannons on here! This is a plane, not the Shell Razor!"
"NOW BOARDING FLIGHT 2085."
Mikey turned to look at you sadly, while handing you the last bag that you had forgotten. 
"Is this goodbye, Y/n?" 
"No way, Mikestar, it's see you later."
"I love you, Y/n."
"I love you too Mikey."
And then you boarded the plane, stopping to wave to Mikey before you finally boarded the plane that would continue your next four years of life.
