The whole episode felt like a cheat to me. All they did was take a previous episode and give it a different ending. I guess the point was that we're in a different timeline now that doesn't match the original one exactly. Well,DUH! Note to Fringe writers: Fringe fans are pretty sharp; we get it without being spoon-fed. Like, you know, the fact that both universes were already working together in this timeline.

That being said, it looks like we're going to get an episode focusing on the "other" universe next week. I can roll with this if they go back and forth like this. But, please, no more flying porcupines.
