Fringe star Joshua Jackson filming scenes as Peter Bishop for episode 507

Back in early October, I saw scenes being filmed for episode 507 of Fringe.

At the time, I didnt really know much of what I saw being filmed the afternoon that I saw Peter Bishop sitting around in an old car. It seemed a bit curious, but a pretty unspectacular scene overall. However, after seeing the promo for next weeks episode

As well as the 2 previous episodes, I now know why I saw Peter Bishop with his collar popped on his leather jacket, sitting in a car with an Observers breifcase.
 
The question now for Fringe fans is, will the final 6 episodes see Peter turn into 1 of the soulless monsters they are trying to destroy, or will his humanity be saved?

Heres some pics from that days filming that took place on West Hastings street.
