No idea if this is true, I guess we'll find out soon... or not.
I'm a Vancouver Fringe fan, and as often happens in cases like this, I know people who work on the show. I have a MAJOR spoiler for you all that I've been sitting on for about a month now out of respect for the people who shared it with me. Now that I'm getting signs that it's about to start leaking for real, I'm going to let it out myself.
Alt-Livia is pregnant and we'll be finding out about it coming up pretty soon. The episode in which we learn this was in post-production about a month ago so it should be airing in the near future.
