I was actually wondering what Kellerman's main goal is. It seems obvious that he's going to assissinate the president, but is it because he was betrayed, to pin another murder on the brothers, or both. I just don't know if Kellerman holds a grudge against them for shutting him out. But, people know Mike and Linc are in Chicago. Wouldn't it be easy to frame them (Linc) again for the murder? Did that make any sense?

Mahone had a little blip there. I think he might start figuring it out again.
