I just started watching this. I assume that Jesse is wrong that Walt killed Mike. As far as Walt knows, Mike is fine, right?
Possible Plot twist: The guy that supposedly gives people an new identity just kills them.
Let me echo the others. Stop reading the thread and catch up. You won't be sorry. Use your DVR for this season's episodes. Trying to connect the dots because you think you have the jist of the show is cheating yourself. The show has so many twists and turns that it's a pleasure to watch.
