Authors Note:

Hey guys, so this is my first fan-fiction for this adorable paring. Re-write of Unauthorized Mission and Bionic rebellion with instead of Chase and Sebastian being Best Friends, they are boyfriends. Some parts follow the show with only a few slight tweaks and added scenes, until half way through bionic rebellion where basically everything becomes original. Some dialogue taken from the show. I just wrote this because I ship these two so much and It must of been tough for chase to be betrayed by his first best friend. But just imagine the pain of being betrayed by your first ever boyfriend. This is a two part fic. This first fic is the build up/ event itself with a little taste of the aftermath. The second fic will be the full aftermath with lots of pain. I'm working on the second one now. This first fic is completed but I'm still working on the second one. But don't worry. I have friends that wont let me give up on the fic, and I am the Queen of Chasebastian after all.

Chapter One: The truth about Chase

Chase had always known he was gay. Well, he'd known since his first week in the real world, which is really when he even began to think about the possibility of dating and all that. So I guess it is more accurate to say that Chase had known he was gay since he first thought about it. It wasn't some big revaluation or something he struggled with. He just realized he was checking out boys like his sister and not girls like his brother.

After a little research, he found out that most likely made him gay. He did look at all the other sexual orientations just to make sure, but 'homosexual' was the one he related to the most. That was that. Less than a week in the real world and Chase had realized he was gay.

Which wasn't the best thing to discover when all you wanted to do was fit in. Chase's research had also shown him that being gay did not help at all when it came to fitting in. He was already having a hard time, being a 'nerd' and all. Plus his sibling already made his life unpleasant half the time by making fun of his height, his looks, the way he dresses, his intelligence and even his personality. He didn't really need to add ' gay ' to the mess that was already his life.

Plus he needed to focus on becoming a better leader and finally going on missions.

So fitting in and his bionic mission took priority over coming out for Chase. But it didn't bother him. He's comfortable with who he is, he knows there is nothing wrong with being gay. But the logical thing was to keep it hidden, to act like he was interested in girls when the time called for it. Which thankfully wasn't that often, because of the whole ' nerd ' thing.

But if a guy ever showed interest in Chase ( one he liked of course ), he knew he would go for it and he didn't care that people would find out. And if someone seriously asked him if he was gay he wouldn't lie. So he wasn't 100% lying, he just didn't think people needed to know. Not that anyone asked him about it or anything. And no one really showed any interest in him.

There was a point when Chase thought that maybe he and Marcus had something. That maybe their friendship could of been a little more. Sadly it turned out that Marcus was an evil android made by his real father to capture them. So that idea blew up in his face.

After that point he started to focus on school and his responsibility as leader of a team of bionic teens. Because that is what's important. Not love. But then came S-3. The cute bionic boy who quickly became his best friend. A friend that Chase desperately needed. Because being a bionic nerd doesn't get you friends. It just makes you lonely.

Sebastian was his first real friend.
