A New Day in the Old Town - S2-E1
Visible crew/equipment: Lighting equipment is reflected on Nina's sunglasses when she tells Broyles to "save the day" after the Senate hearing. (00:31:40)
Visible crew/equipment: When Walter and Olivia leave the hospital in the alternate universe, William Bell pulls up in his vehicle. As he does, you can see the reflection of the crew on the metal bars in the front of the vehicle, as well as the metal side-view mirror.
Answer: In the time line of Season 4, William Bell is trying to destroy both universes to create a new one, and he needs Olivia to power the collapse. So he helped her escape. But the real question is, if not in search of Peter, why Olivia has to travel to the alternate universe to be captured and replaced?
