I was racking my brain last night because the end seemed so familiar Then I remembered it was similar to how Burn Notice ended last season
Good finale..so no more Dr. Bell it seems I wonder if she will keep her cover and still solve cases for Fringe Division.
She'll be outed soon. She didn't get enough info from "our" Olivia to get by for very long. And the universes are really quite different.
As for the writing: When "their" Olivia said that she had to use a phosphorus grenade how did she know about it? Wasn't that something that Bell had not given to the Fringe division just like he had not given them the 77 pistol? When he gave it to "our" Olivia it seemed that it was still a work in progress. The writers need to be careful about those things.
On the other hand "our" Walter performed a major screw up by bring Peter back because he really jacked that other universe up. I'd be pissed at him too.
