Yay! We get to check back on the other universe with the fun Fringe Division. Fauxlivia is reunited with Frank, back from his good doctoring. She seems a bit distant, which he notices, but she plays it off as being busy with work. This week's work is set in motion when a dour middle-aged man slips something into a poor schmuck's drink at an airship station. Soon after, the schmuck is barfing up hundreds of roachy insects, one of which the dour fellow collects as if it were a precious gem. Fringe Division is called in to investigate, with elfin Lincoln leading the way now that Broyles is "missing." Their search takes them to a cute lady entomologist who's warm for Charlie's spider-infested form. She tells them that the roachy things are parasitic "skelter beetles" (oh, show) that died out when all their sheep hosts went extinct ten years ago. Their search then takes them to a Dr. Armand Silva, who was working on a cure for bird flu that involved skelter beetle enzymes. He's revived the beetles using human hosts to incubate them. It's so complicated.
Also complicated is the fact that Frank is brought in to work with the team. He proposes to Fauxlivia and she accepts. Everything seems relatively fine until Faux and Link go to nab Silva in his makeshift lab. There, Link gets locked up in a freezer and Faux gets trapped by Silva. He starts spouting some crap about needing one final host to breed a queen beetle. Faux thinks this means she's been infected and promptly barfs. Link busts out of the freezer to save her, but it turns out Silva infected himself. The birth of the queen kills him, but he seems satisfied that at least he'll be remembered for curing the bird flu. And killing a bunch of people. So why was Faux suddenly nauseated? As Frank rushes her into an ambulance and performs an ultrasound, he discovers the answer: she's pregnant. In fact, she's six weeks pregnant, which means Peter is the father. Drama!
In the B plot, Walternate and Brandon are testing Cortexiphan on several adult subjects. Most of them die within minutes. The youngest survives long enough to develop telekinesis. Brandon suggests the try the drug on children, but Walternate refuses. He's distraught that this might mean his weak, but a smoking hot Joan Chen is there to comfort him.
Previously on Fringe: Olivia and her Fauxlivia doppelganger swapped universes for a while; Fauxlivia's boyfriend Dr. Frank left on a mission of mercy; Peter and Fauxlivia started dating, but he eventually uncovered the truth; Fauxlivia told Peter things may have started out as an assignment but became "something more"; he didn't quite believe her; Over There, Colonel Broyles is "missing," and that's because he was chopped up and sent Over Here in a universal balance swap with Fauxlivia.
Currently on Fringe: An airship putters through the night sky. The ship makes its way toward the top of the Empire docking station, inside which Fauxlivia is waiting. Her hair is auburn again. She watches through a window as the ship approaches, then watches as passengers disembark and greet their waiting loved ones. For a moment, she seems more like regular Olivia, because there's an "outsider" quality about her. She's like an alien observer in her own world now. A man comes up behind her and covers her eyes with his hands. "Guess who?" asks Frank. She touches his hands and jokes, "Well, the voice isn't familiar, but the hands I like! Rugged and sexy." Definitely not regular Olivia. She turns around to face him, all smiles, then pretends not to recognize him. He keeps up his end of the ruse, going so far as to act like he's going to walk away. She pulls him back and says he seems familiar, after all. "Maybe it's the lips," Frank offers, kissing her. They smooch and canoodle and leave the docking station together, Fauxlivia's arm draped over Frank's shoulders.
As they walk past the lounge, the scene's focus switches to two men sitting at the bar. The younger one of the two watches TV and drinks while the older one regards him with a sort of sour studiousness that seems like distaste. Then he cheers up a bit and makes smalltalk. "Everybody complains about the weather, but nobody does anything about it," he says. The other man ignores him. "I'm quoting Samuel Clemens," he says. The accidental tourist looks over at him and they commiserate with each other about their plans being delayed. The older man fidgets and looks around, then asks the other to pass the salt. When he turns away to fulfill the request, the older one swaps their drinks. He watches nervously as the other man drinks from his new glass.
Fauxlivia's apartment. Frank emerges from the bedroom all freshly showered and bemoaning the lack of such civilized luxuries in North Texas. I'd love to know if North Texas is a separate state from South Texas in this universe. Fauxlivia brings him a glass of red wine while she sips lemon water. Her smile is shy when he thanks her. She hurries past him and heads for a bookshelf, fiddling with a CD case like she's looking for something to do. "Everything all right?" Frank asks. She pretends to not know what he means. He says she didn't say anything on the drive home. She seemed "distant" when he called her from Texas. She saunters up to him, slides her arms around his neck, playfully says they were distant. "You didn't seem like yourself," he says. There's a subtle look of panic in her eyes, but she recovers quickly. She says work's been crazy, which is kind of an understatement. Work is pretending to be another version of yourself in a parallel universe to ferret out the secrets of an ancient, world-destroying machine. He seems mostly swayed by her explanation. To seal the deal, she says, "It's just things are a little overwhelming since Broyles went missing." She moves away from Frank to shut the Peter folder that lies open on the coffee table. Frank asks if there have been any leads. Fauxlivia says his car was found "on the edge of a no-go zone," but that nobody knows why it was there. "Something classified?" Frank offers. "Possibly, yeah," she says. She lies more easily about this than she does about their distance. "Lincoln's taken over in his absence," she says. "He keeps pressing all the official channels but we're not getting any answers." With what seems like genuine sadness, she says they've stopped the search. Frank wishes he could have been there for her, but she's just glad he's here now. They kiss and smile and everything seems fine.
