Later, the police, with Mulder and Scully, pull up in front of the motel. A nearby police officer tells the agents that no one's gone in or come out of the motel room since they've been there. Mulder, Scully, and one of cops approach the motel room. There is a sound of breaking glass. Everyone looks at each other, and Mulder kicks down the door! He, Scully, and the cop creep inside the motel room, guns drawn. Inside, they find Sally Kendrick in a pile by the stove, knife in hand. The twins -- the evil, evil twins -- are huddled in the corner, holding each other. Behind them, the window is broken. Scully checks Sally Kendrick's pulse. She looks at Mulder and shakes her head. She then goes to comfort the evil, evil, evil twins, who tell her that Sally Kendrick and "the other lady" tried to poison them. "We only pretended to drink," one of them whimpers. "What did the other lady look like?" Mulder asks. One of the twins shakily points at Sally Kendrick's dead body. "Eve Eight!" Mulder says. "They were working together." Scully makes sympathetic Mommy noises and pats the girls. The twins look at each other, thinking that this G-Man (and Woman) are really, really dumb.
Moments later, Scully finds a glass containing the digitalis. She tells Mulder that foxglove has a sweet taste, so that it wouldn't even be perceptible in soda. They're looking at each other thoughtfully when a police officer approaches, and informs them that the cops can't find the other perp. Looking bored, he says something about taking the girls to a foster home or somewhere. Mulder offers to take the girls with him. Scully mutters something about getting them checked out at the hospital. The cop is all, whatever. Literally. He says, "Whatever."
So Mulder and Scully load the evil, evil, evil, murderous little girls into the back seat of their rental car. "What's going to happen to Cindy?" Teena asks. I think it's Teena. They might have pulled a switchero, like in The Parent Trap. Except, you know, evil. Mulder says they'll talk about in the car, and shuts the door on them. Scully waxes poetic about how hard it will be to separate the twins, now that they've bonded and all. Behind her, the girls plot shit.
