Fringe: Will they or won't they?

I watch Fringe every week on TV3. To be honest, it is one of the only programmes I sit down to watch every week, considering my hectic journo lifestyle as you can imagine.

It's flipping quality programming but there is one underlying thing that bugs me every week and that is the sexual tension between the main two characters, Olivia Dunham and Peter Bishop.

Every week, they end up in a situation which calls for a little bit of moral support from one or the other, either in the form of a hug, a touch, or a nudge, but so far, no tender loving kisses have been exchanged.
Obviously, Joshua Jackson who plays Peter Bishop used to be Pacey out of Dawson's Creek (and he certainly got around the whole creek) so maybe he wants to play a new character that thinks with his big head rather than his little head, but what is the story with the Olivia Dunham character. She's lost her fiance weeks ago and has still not got over him by rolling around with Peter yet. The dilemma is just as strange as the problems they solve.
I'm just wondering though, if they do hit the sack together, will this eliminate all the palpable tension on the show and cause it to pure muck. I hope not.
