Also, I don't know if you guys caught this or what, but after Jesse and Walt shook hands and Jesse was leaving, the camera was angled from the perspective of someone hiding. If you listen closely, you can hear what sounds like breathing. This makes me wonder if Mike played a role in helping Walt. He was clearly acknowledging someone in the car at the end. Who else would have that air freshener? You could say it was Gus' car, but unless it was moved, it wasn't parked in the same place as it was in 'End Times', at least from what I saw.
