Back during the earliest issues of Avengers Academy, Christos Gage let it slip that one of the students would go evil/become a traitor.  The question is who?
At this point, I think it's pretty safe to say it's Hazmat.  She's doomed to a cruel fate, and it would make her the most tragic kid to fall.  We seen that she could have been happy, but finding out her fate seems to have made her more bitter.  There's also how unreasonably cruel she was during the recent Spider-Man issue.  Not to mention she is the most powerful of the kids.
What are your thoughts?  Is Hazmat the traitor or not?

Maybe so...but that seems a bit too obvious.

I'm hoping it's Finesse so she'll join up with Taskmaster. Their battle was a highlight of the series.
