Last time we saw Till I thought a lot about how, to an addict, therapists are like cops: they exist to help you, to fix the problem, but when they do it can really suck. And the threat of Till for Nancy always seemed to mirror the threat of rehab for Celia. But when the addiction is the game, itself, those two jobs are even closer. Till says the things you don't want to hear, and enforces the rules you think you're beyond. He's like a moral compass too.
"He's a killer!" Ignacio says, in contrast to himself, who will kill Till in a moment if she lets him, and they can go watch Milo & Otis. They start kick-fighting, hands chained above their heads, and Nancy yells at them to settle down. "I'll make you pee your pants again!" she shouts, and they chill a bit. Till asks whose side she's on, and caught up in the fight, Ignacio yells that she's on his side: having a baby with his boss, in fact. She shoots Ignacio a hurt, annoyed look that is almost worse than the taser, and he's contrite. "What's it like, fucking a monster?" asks Till, and she nearly starts crying, but kicks him viciously instead, over and over, biting down on it.
So the choice is who to free, because they can't both be there forever, but whoever she frees they're going to kill the other one. Go with the good guy, he'll kill you and the bad guy and probably your family. Go with the bad guy, and he'll kill the good guy, and you will no longer be a good guy. So, by the additive property, the choices are: be the bad guy, or be the dead guy. As per usual. Of course, Celia chooses this moment to let herself in downstairs, and the kick-fighting starts again until Ignacio notices that Till's getting a hardon. Hilariously, Roy chins that it's a "perfectly normal reaction to the adrenaline of combat," and keeps kicking at him, but Ignacio, in a hurt tone, whines that he doesn't want to fight with Roy anymore. It's pretty darling, the whole thing.
The door was open. Well, it was ajar. Well basically, it was unlocked. Nancy stares at her, hatefully exasperated, and somehow summons within herself the ability to put down the taser. Well, using it would just make more of a mess, in more ways than one. Celia's next plan is a doozy: she realizes that, due to being utterly despised at this point by Nancy, she can't live in the house proper, but she's willing to compromise and stay on the couch in the balmy screened-in porch out back. Nancy responds by lighting a match and throwing it at her. "Hey," Celia yips. "That's fire!"
