In effect, Cathy cruelly translates, he needs her to save his life. To keep him from dying in his sleep. She knows that's not what he means, that she's just being a bitch, but right now she doesn't care. She knows he doesn't have the capacity or the vocabulary to actually express what he means, which is that he is built for two.
Paul shrugs and tries to sell her on their teamwork, partnership, all the little ways they help each other out. Team Cathy has left groceries on the porch -- Cooking up some healing thoughts for you! -- but of course Paul thinks that she left them there herself. "Which by the way could be a sign of early Alzheimer's. See? We do need each other. And you're welcome."
Cathy sighs and leaves to take Thomas back to Marlene, again, and he calls out commandingly, "I'm gonna win you back, Cathy." She admits, honestly, that she wishes he wouldn't, just at the moment.
Cathy takes Thomas into Marlene's house, since she's not on the porch, and Marlene complains that she never knocks. "Neither does your dog. He was in my bed this morning. He's clearly lonely." Marlene's surprised, but something catches in her voice: "He was in your bed?" Her mouth describes a fine line and her back goes curved and fight drops out and down through the floor, because she's got the message now. Marlene plays solitaire, a game built for one. "Sorry if it put you out," Marlene says, brusque; trying to keep the fight in her voice, trying to keep the pain out of it. The pity. "And you may want to wash wherever he licked," she says, for good measure. "Thomas likes to eat his own poop."
For a hundred bucks a pound Andrea will ride the tandem bike. For a little while. "My cooch is getting sore," she sighs, and when Cathy reminds her that she'll feel great when she drops a dress size, Andrea almost laughs: "Who the fuck wears dresses?"
Cathy hands Andrea a bottled water -- wouldn't Sean be proud -- and invites her to dinner tonight. Why? "Because I like you, Andrea." (Sean, Adam, Daphne, what could go wrong?) After a little bit of fucking around Andrea declines: "This better not be like one of those Blindside fantasies where the uptight white bitch tries to save a black kid." Cathy says she'd settle for keeping Andrea alive until graduation. "Way to dream small, Mrs. Jamison." It's a passport she's trying to give her.
Daphne and Sean are not interested in the pigs-in-a-blanket, of course, and Andrea pronounces them "crazy-ass" white people food. Cathy tells her she can have a couple, and then Sean and Daphne start telling her the disgusting story of hot dogs. "I love it when we finish each other's sentences!" Daphne squeals, and Cathy hands her a passport to the fact that it's a sentence nobody wants to hear.
