8. The Alternate Universe
We havent heard from the Alternate Universe since the bridge was closed towards the end of Season4 with Lincoln having joined Fauxlivia on the other side. The thing is, we never did quite get to the bottom of what had been happening over there. Having spent the first three seasons at war with our Universe things appear to have settled since the bridge was built and Universes subsequently fixed, however Walternate was always depicted as vengeful (he was behind the future terrorist attacks in one timeline) and is unlikely to have forgiven Walter. We also havent heard if the Alternate Universe has had any troubles with the Observers, or what happened to their Fringe team.
The Questions: Is their Universe fixed? Are they also under attack from Observers? Is Walternate still plotting against Walter? How much of their Universe changed with Peters deletion from time?
