I don't know, I really do believe that Jesse can't find it within himself to kill again. I can't see him breaking down in NA one week because he can't bring himself to forgive himself for what happened to Gale, and secretly planning another murder the next.I think Jesse is just bidding his time with Gus, getting rid of Walt's plan to kill Gus and trying to come up with a better plan to get the job done by pretending to be one of the guys and keeping his eyes open.
Another great episode, I especially loved Walt squirming in the car with Hank while Mike sinisterly smiles in the next car.
