Re: Fringe 4x19 - "Letters of Transit" (Live Commentary, Spoilers)
It's not certain which universe this episode took place in, since we know Bell is dead in the new Peter-less timeline, then Bell might have survived in the new Peter-less timeline in the other universe. The new Walter might have been the Secretary. The brain damaged version seemed like an exaggerated version of the original Walter. And Astrid didn't get enough dialogue for us to be sure she wasn't just an non-uniformed version of the other universe Astrid.
