Johnny Broadway has jazzed up his black clothes with a bright red jacket for opening night. He comes bounding down a spiral staircase and encounters Friedman in camo gear, with a big plastic gun, rehearsing his lines: "Eat lead, zombies! Eat lead, zombies!" Johnny Broadway tells Adam, "Loving the trees!" Adam's setting up a large board featuring the periodical table on an easel. A student in a blond wig and white lab coat seems ever so slightly Lischak-esque. I'm starting to miss her. We haven't actually seen her since the third episode this season, have we? She's been mentioned a lot and there have been scenes in the science classroom, but I don't think we've actually seen her. Did she get a role on another show or something? Carl approaches Joan, whose hair is pulled back and who's all made up with white face paint, and it turns out he's about six and a half feet tall. Or maybe Joan's only four feet or something, but either way, he towers over her. He asks if she'd like to run her song with him. Joan frets, "I'm totally going to forget the words." She's wearing a sheer white dress with a high neck and long sleeves, and a sparkly red belt. Elizabeth, wearing a very pink off-the-shoulder dress and very bouffant hairdo and sitting nearby in front of a mirror, says, "You have to visualize it…written in the lights." She looks up at the ceiling to emphasize her point. "So, instead of looking at the audience, you pretend that you're reading it, up there. Like it was written just for you. Because it is the best song." Joan insists, "Elizabeth, I didn't want this." Elizabeth says it's okay: "My therapist says that with a voice like mine, I need to work on humility." Oy. She takes Joan's hands and says, "Break a leg. That's just a saying." Joan: "Mm-hmm."
