a/n: This has been sitting in my head since Mixed Signals. I hope Six is IC. Reviews are always welcome.

18 months. For 18 months I've been Rex's…babysitter. With no memory of his past, of who he was before I pulled him out of the rubble, someone needed to look after him. And I, being the one who found him, was given the "honor" of being his guardian. Why they placed someone like him under the care of someone like me, is beyond me. I am…was…training, competing to be the most dangerous man on Earth. And this boy, this child, now clings to me as though I'm his father. Not that I can totally blame him. I was there once, a long time ago. The feeling of loss, of lack of purpose. Then someone comes along, sees something in you, and doesn't walk away like all the others. In a way, I'm Rex's One.

Since the beginning, I've been searching vigorously for his family. Maybe if he found them, I would get my freedom once again.

Now, 18 months later, his family shows up on Providence's front step. Caesar, his brother. I should be happy, even though I'd never let it show. Now that Rex has a brother, I won't need to be his guardian anymore. I can go back to competing to be number two (One is always going to be number One). But something doesn't feel right. I can't place it, but something is missing. Holiday confirmed that Caesar is Rex's relative, she did something using DNA, something sciency…the details are beyond me. And he seems to know about Rex's past, but something is off in him.

I am not a people person, not that I'm an animal person either. I don't like being in the company of others, but usually I can tolerate it…usually. With Caesar, I have a feeling that he deserves a katana through his heart, assuming he has one.

I can't explain it, but I feel the need to protect Rex from him. Holiday and Rex may be blinded by the fact that he is Rex's brother. They see Caesar as a blessing, a scientist from the nanite project, and a person from Rex's past. He's smart, maybe a little kooky, but he helped stop the pentapus EVO when no one at Providence could.

He saved us from a potential Bleach; he's helpful.

But something's wrong. Not that I would know, but a brother who has been gone for 5 years should immediately check on his family, not some nanite. For the past 18 months, Rex has harped on his lack of family, and more recently his brother (ever since Rylander mentioned his brother, Rex never seemed to be able to talk enough about it). Well, we found him. Actually, he found us. Rex is happy. I'll be happy for him. But I'll still keep an eye on Caesar.
