Oh, god. Why do we have dream sequences? Why do television shows think dream sequences are any more interesting on TV than they are when the office basketcase bends your ear by telling you about the "crazy" dream she had last night? Why?
In this case, Sarah's the one having the dream, in which there's an open grave, and she's watching herself next to Cameron, both of them in pink dresses, and Cameron's watering the ground. It's like Little House on the Fucked-Up Prairie. Cameron's watering a cactus, and then three cacti are sprouting and growing as fast as anything in Super Mario Bros., and then suddenly John is standing there, and the cacti, now fully grown, turn to metal, and one wraps its arms around John.
Sarah jerks awake in the back of a truck. She tells John, who's driving, that she's going to be sick, which is probably due to all the bouncing and jouncing they're doing, all the better to show off the handling and suspension on the gleaming specimen of a vehicle from a company that pays a lot of money to this show.
John stops the truck, and Sarah hurtles from the back to hurl her cookies all over the ground. John and Cameron get out as well. "What's wrong with her?" asks Cameron, looking awfully disgusted. She asks if Sarah's pregnant. "Why in hell would you even ask that?" snaps John, and Cameron explains that Kacy vomited in the morning when she was pregnant. "Was"? Please tell me she's finally squeezed that thing out. Sarah says it's just a bug, or stomach flu. Luckily, for exposition's sake, they've stopped near a sign that says "Tijuana 39," and John says they'll be home soon. He goes to help his mom get back in the truck, but she's spotted an upended turtle near a wheel on the truck, and she rights it, moving it to a safer spot. Cameron watches.
Later, back at the Connor Compound (is this the same place? shouldn't they move?), Sarah's asleep in bed. She wakes as John comes in with some medicine, and he asks how she feels. "How do I look?" she asks, and he says, "Like crap," like way to cheer your mother up, and she jokes that she wishes she felt that good. And in comes Cameron with a tray of "rehydration fluid," which Sarah should check to make sure isn't Pennzoil. Cameron tells her to drink one cup every half-hour or right after she vomits.
Sarah tries to sit up, and John won't let her, even though she wants to go back to Mexico with the thermite to dispose of Chrome Artie once and for all. John points out that the body is buried in a hole in the Mexican desert and the chip has been obliterated. He's about to say he thinks that they're safe, when Cameron interrupts to say that they're not. John says she's starting to sound just like Sarah. "She's right," says Sarah.
