BECKY'S ELIOT came for two reasons. One: support his brother from another mother universe. Obviously, he can't allow himself to be shown up by his facetwin, but this time its much more in a friendly competition way. Two: he's dragging Alice. Margo, too, obviously, but Eliot is trying to distract Alice from the heartbreak they're both feeling from last week (Eliot's for multiple reasons).
JULIA came. She's not 100%, still a little banged up from the wampa kidnapping and emotionally hungover from Sylvie's memory spell, but she's showing up. She's going to sit in a chair, force herself to smile and pretend like everything is alright.
STEVIE did not come. :( This would be right up her alley. I mean, perhaps someone tried to convince her it would be okay, but unless it was Carver, she's probably staying in her room.
HARLEY showed up. She found fucking roller skates. Where did she find roller skates? Who knows, she found them anyway and is dancing in roller skates. Watch out for this one, she will steal your drinks if you have alcohol on you.
