Etta is used to seeing Penny cover up her feelings, and doesn’t try and make it worse by insisting that this is a big deal, since she knows Penny would hate that. She smiles awkwardly and says, “Oh -- Sun-mi. I’m going with Sun-mi.” Ah, shit, way to rub it in, Etta. She’s not usually the type to repeat herself, but it still hasn’t quite sunk in for her yet either.
