Inner Child - S1-E15
Continuity mistake: Olivia, Broyles, Peter and Walter are visiting the boy for the first time at the hospital. A small bit of Olivia's hair is in front of her left shoulder. Cut to the immediate next shot from the patient's room and all of her hair is behind of shoulder. (00:07:05)
Inner Child - S1-E15
Continuity mistake: This is when Olivia goes to visit the boy at the hospital the second time. She and the guy from Department of Social Services go outside to talk. One of the shots is flipped. Note Olivia's notepad and the heart monitor by his bed. (00:19:40)
Inner Child - S1-E15
Continuity mistake: Olivia stops The Artist at a checkpoint, and he touches his face with his hand. When the shot cuts to Olivia, his hand disappears; when the shot cuts back to The Artist, his hand reappears. (00:43:20)
Inner Child - S1-E15
Continuity mistake: When Olivia calls Broyles to ask him to move the child, the shot of Broyles answering the phone is a recycled shot from the episode "Safe". In addition, the shot is flipped, as can be seen by the fact that Broyles' watch is on his right wrist rather than his left.
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?
