I don't know why they keep referring to the towers in the singular, because there are two of them. I mean, they're connected, but it's still two thingies. I'm going to keep referring to them in the plural. Screw the show and their inability to count higher than one!
Back to the shower of doom. Vala's shower stall is held aloft by chains and pulleys, which suddenly crank into motion so that she turns to face the man in the gas mask. She whimpers and gasps. The man takes off the mask. Underneath, he's wearing a black watchman's cap. He has very pretty eyes for a psycho. He also looks like he hasn't shaved or cleaned up in a while, though. Vala begs for her freedom. Psycho says, "Oh, I don't want you contaminating things, alien." She protests she's not an alien. He exposits about how he'd thought all of the aliens had left Earth, but when he saw Vala and the others he knew they were planning to colonize the planet. Vala continues to protest, but Psycho says he's gathering proof. "I'm going to share it with the rest of the world," he says. "When they learn the truth, all of you will be hunted down and exterminated." He says the last through his teeth. He cranks Vala's shower stall so that she has a clear view of a severed arm that's hanging in a display case. A Kandorian tattoo marks the flesh. Vala screams. Psycho picks up a saw and starts hacking away at someone on an examination table. Blood spatters everywhere. Hope y'all weren't enjoying a nice spaghetti meal during that. Commercials.
