[…] the meantime, Olivia meets with Sam Weiss as she had planned to do last week in an attempt to move on from her accident. He begins to ask her if she is having trouble sleeping […]
In the beginning of the episode, Olivia is finally ready to check out of the hospital. Charlie watches her leave. (But remember Charlie was killed by a shape shifter that is now pretending to be Charlie whose assignment is to get Olivia to confide in him about what happened with William Bell). While she is checking out, Walter continues to investigate her disappearance but still can’t explain exactly what happened to her.
The Fringe team (including Olivia) is given their next assignment, to follow up on a construction worker who has gone missing in Pennsylvania, the seventh disappearance with the same circumstances. While they are there Walter gets some blue goop, Peter gets the town’s citizen files from the local sheriff.
Walter figures out that the blue goop is a paralytic and partially comprised of human DNA. Then, while studying the town’s records, Olivia is able to tie one man to the scene all of the disappearances: Andre Hughes, formerly a doctor.
Peter and Olivia head back to Pennsylvania to question Andre. Olivia, who now has heightened senses, swears she hears someone else breathing in the house but doesn’t find anyone. Andre reveals his wife died giving birth to their child many years ago. But he won’t let them draw his blood to see if his DNA matches the goop, making the team suspicious. To complicate things more for the team, Andre crafts a noose out of the mesh lighting wire in his jail cell and hangs himself.
Olivia accepts the card of a Sam Weiss from Nina. Since Olivia is still recovering, Nina offers her the help of Sam, whom she thinks will be able to help Olivia deal with what she’s been through.
Walter gets the team to exhume the graves of Eve line and Baby Boy Hughes only to discover that the baby boy has burrowed his way out of his grave. Back at the lab, Walter performs an autopsy on Eve line’s remains and finds she had advanced Lupus which would have prevented her from having children. Walter thinks that Andre altered his baby in the womb so that it could survive in spite of its mother’s Lupus.
Olivia and Peter go back to Andre’s house and eventually make their way to the basement where they find a tunnel (like the one we saw burrowed under Baby Boy Hughes’ coffin) in the wall. As Peter searches for a shovel, Olivia is attacked and dragged violently into the tunnel by some kind of beast. She also finds the victim from the beginning and local Officer Golightly.
Peter comes to the rescue (again) and wounds the creature, which burrows its way out of the house and collapses in the driveway. A car comes crashing through the earth, crushing the beast. When a swarm of FBI agents arrive later, they discover a number of bear traps. It looks like Andre was trying to catch the creature before it took more lives.
Back at her apartment, Olivia relaxes in a hot bath but realizes she can hear everything-from bugs crawling to far off traffic. This is enough to force her to take Nina’s recommendation about Sam Weiss and she meets with him in a bowling alley.
Finally, “Charlie” gets his next set of instructions: DO SOMETHING TO HELP OLIVIA REMEMBER WHAT HAPPENED
