I don't like this episode just for one thing, it confuse me more by the fact that doesn't suppose to be that the Broyles from the other universe die in the season 2 finale? I know that Peter, by his no-existence, could change things, but i don't get it, how can Broyles-nate could be alive.
I think that Fringe writers better explain it or don't show him (Broyles-nate) any more, is just stupid kill someone and then bring him alive by no reason. I keep wondering that if Peter change the course of previous events, then I hope that Faux-olivia's child doesn't exist either, it would make sense because Peter never 'exist'. I hope that what we seeing in Fringe won't be a stupid storyline, that leads with no explanations and let us with more questions than answers.
I like this show, it's in my top 5 most to watch shows, but I would like something that make sense, no something that is tricky without any mean.
