In a perfect world, it would be all about Peter and Olivia. But in Fringe's alternate universe, there's that damn Fauxlivia to worry about, too. And with young Mr. Bishop still harboring the warm-and-fuzzies for his Mata Hari from the other side, not to mention a pileup of major revelations that come out in this week's episode (Friday, 9/8c on Fox), things just can't be black or white... or in the show's multiverse color scheme, red or blue.

Who should our hero pick, Liv or the liar? In this exclusive video, the cast discusses TV's trickiest threesome, Peter's, um, bedroom abilities, and how the fate of mankind may actually rest on his decision. So check it out and then check in with your comments on whom you would like to see Peter with. And don't worry, Massive Dynamic will not be monitoring your answers below. At least, that's what they told us to say.
