Then there's a kind-of multi-colored flash, and the singe marks remain but the windows are all back to normal. Also, Samantha -- still in her mother's arms -- is five years old again. "Mommy, what is it?" she asks, as her mother hugs her. It's nothing, sweetie. Your mom's just losing her mind, that's all!
After the opening credits, Peter's in the car with Olivia, and he's looking around outside. "What are you thinking?" she asks, and he says it's the first chance he's had to look outside since he got back. She's all, "Duh, I mean about the time anomalies I told you about." He characterizes it as people having strange cases of déjà vu, but she says it's more like time loops. Peter makes a Groundhog Day joke, and then asks what it has to do with him. "Shortly before you arrived, we experienced our own anomalies having to do with time, strange reversals in cause and effect," she says. That's why they're taking him to Massive Dynamic, to run more tests; they think the time anomalies may be because of him. Peter asks what Walter's theory is, but Olivia says Walter doesn't have one: "He's made it pretty clear that he doesn't really want to have anything to do with you," she says.
No time to explore that further, because Olivia gets a call from Lincoln Lee to tell her there's been another incident. On the scene, Astrid is using some tech borrowed from the other side as Walter walks her through the instruction manual: "'A short emission should indicate universe breach and extend through the infected area,'" he reads, but the spray, out of two light-blue cylinders, reveals nothing even after Astrid sprays the burned-out kitchen three times. Walter concludes that whatever happened here, it wasn't caused by a bleed-through from the other universe. "Well, it's a wonderful device nonetheless, despite the poorly written instruction manual," he says. Maybe it's not working right! Tell Astrid to blow on it!
Meanwhile, Olivia's taken a detour and brought Peter inside and tells him to just stay there and not touch anything or talk to anyone. I'd like to point out that Peter's a prisoner, so I'm not sure this would be proper FBI protocol, but never mind.
Anyway, Broyles fills Olivia in: it looks like there was a fire here, but the damage happened in an instant and there were no flames. But that's not the weirdest part: "According to the mother, for the duration of the event, her daughter went from being a five-year-old to an infant," says Broyles, and Olivia's eyes go all, "Say whaaaaat?"
