Frank's return from North Texas means Olivia's life can get back to normal. Or so it would seem. She still has Peter Bishop on her mind. Frank finds her distant, which she attributes to stress at work.
The Fringe team adjusts to the mysterious disappearance of their leader Broyles, as they deal with a case of skelter beetle infestation in people. These extinct parasitic insects that only lived in sheep have been re-engineered to live in human hosts. The investigation lead them to one Armand Silva, a scientist who was infecting people to develop a vaccine for the avian flu. During the course of the case, Frank discovers Olivia became pregnant while he was away and leaves her.
Meanwhile, there is a breakthrough experimenting with the cortexiphan synthesized from the other Olivia's brain. Brandon theorizes the it would work better with younger test subjects. The Secretary objects to testing on children. Later he would confess to his mistress about his decision.
If you had asked me a week ago, I would have told you that I would sacrifice anything... to save our world. But in fact, there are lines I simply cannot cross.
- Brandon has been busy dissecting the brains of the test subjects in the drug trials. Just as he proposed to do to Olivia before she escaped. (Entrada)
- Frank teasing Olivia at the airport was the cutest scene ever. Their chemistry here was way better than in "Over There, Part 1". These are rare happy moments in Fringe. Their last kiss was a lot like Liv and John's in the pilot.
- Frank's marriage proposal. Who is his mother? He mentioning her must have some relevance.
- Who is Reiko? They wouldn't have cast her for such a small part for no reason.
- Bug girl Mona Foster becomes Charlie's girlfriend. We learn arachnids are living in his bloodstream and that they itch sometimes.
- Frank flirting with Astrid. "Where do I get one of you?" Is he like that with just any girl?
- What Charlie said about the augmented bugs. "They look the same, but they are not the same."
- The Secretary changed his tone after this. Would he really have reconsidered activating the machine if Peter had went back?
- As much as I like Frank (He was kind of perfect.), I can't really feel sorry for him. One moment he proposes marriage, saying he can't stand being away from her, the next he just packs up and leaves. Poor Liv. Olivia said yes, because there was no doubt that she would have settled into a comfortable life with him, despite her feelings for Peter. I suppose it was too soon to expect happy endings. To make things worse, the Secretary will start keeping close tabs on her.
If Peter Bishop Never Existed...
Olivia would not have been pregnant. She and Frank would be honeymooning on some island paradise, living like... oh... I don't know... Robinson Crusoe maybe.
