Freak of the Week: People still use shortwave radios? I guess so, because a bunch of people around the world are using them in some kind of shortwave radio chatroom. They all receive a transmission of numbers, have a seizure and, get amnesia.
Peter and Faux-livia are all cozied up with breakfast in bed as if they're in a lovely, long-term relationship, until duty calls. I'm not too gung-ho about Peter and Olivia hooking up, but I'm OK with it this way since it's not really Olivia. Just makes for more angst once that's revealed!
Walter's pissed at Peter because he's still working on the Otherworldly Peter Death Machine. Nina has a heart-to-heart with Walter over some weed, telling him he should let Peter continue his investigation.
The shortwave radios pick up number broadcasts, some kind of codes transmitted by who knows who. But along with the numbers, some dude is transmitting a pulse that gave them amnesia. He does it again later with a transmission to the pilot of a small plane.
The investigation leads to the First People - people before the dinosaurs. The numbers are the keys to the universe, and the dude wants to keep people from discovering what they mean.
Faux-livia goes to see the dude, who is from the Other Universe, working for Walternate, to scold him for being sloppy. Just as he's about to be discovered, Faux-livia pushes him out of a window and he splatters onto the ground at Broyles's and Peter's feet, leaking mercury. He was a shapeshifter.
Astrid, kind of channeling Other Astrid, cracks the code. The numbers represent several locations around the world. The closest one is in New Jersey, and buried deep beneath the ground (wow, they really took a chance that Astrid was right - they dug a bigass hole) is a large stone thing containing part of a machine. One of the locations is also Walter's old house in Massachusetts. The locations are all pieces of Walternate's Death Device.
At the end, Faux-livia receives instructions through the Otherworldly Typewriter. Initiate Phase Two.
Walter's Line of the Week: "I feel a bowel movement coming on." Goddammit, Walter, that was just unnecessary!
Walter's Food Thing of the Week: Cucumber and cheese sandwich - the best food for thought, as developed by Walter. It worked on Astrid!
This Week's Code: DECAY.
