I'm going to be optimistic and say that it ends with Olivia telling she's pregnant, or Walter telling Olivia and Peter, whatever Although I would prefer for that to be a PO moment only.

I don't know, this entire Bell new world already looks too crazy. That scene of Walter and Bell contemplating the new world doesn't feel like Fringe to
me, it really looks like FOX told the writers "look we cancelled Terra Nova, now you guys pay some tribute to them because we chose you"
