Last week I was thinking, wow, the fate of 2 universes rests on a romantic relationship? That's the kind of fearless that I admire about
Fringe. (Even though it no doubt annoys the noromos.)
This week, as soon as Frank points the ultrasound wand at FauxLivia's belly, I know she's pregnant. And I'm...

This backs up Sam's statement to Nina last week about not being sure Peter will pick our Olivia, but it seems so... not-fearless.
Unless it's some grand scheme by Walternate, sending FauxLivia Over Here to seduce Peter, get pregnant, and make sure he goes back Over There of his own free will. Except nobody has been playing it that way.

Which makes FauxLivia pretty dopey. Mata Hari doesn't get pregnant! Especially with a boyfriend back home.
A few weeks ago, the episode where the Observer is pointing his Whammo weapon at Peter and says, "It must be difficult, being a father..." Someone at another board wondered at the point whether FauxLivia was pregnant. I thought, naw, they wouldn't do something so conventional, would they?
I do like the notion mentioned upthread of a parallel situation where Peter is compelled to steal his child from the other universe.
And alt-Brandon gives me the creeps. "I'll know more after I've dissected his brain..."

Who knew Walternate would end up looking more morally upstanding than mad-scientist Brandon? Although Walternate seemed to be regaining his creep factor in that last scene with FauxLivia.
