Sandrine in Act One, Scene Two: "Sad and Glad".
“Sad and Glad,” follows Jimmy and Sandrine, who had split up a while ago, running into each other at a local hangout. Over the course of their conversation, Jimmy tries to see if Sandrine will come over because he misses her, but Sandrine tells him she’s getting married the next day. The conversation grows even more awkward as Jimmy tries to get the waitress’s attention to order celebratory drinks, and Sandrine sees he’s gotten a tattoo—Villian, a misspelling of villain—after they broke up. Sandrine leaves and the scene ends with Jimmy’s realization that the waitress’s name is Villian, which gives him something to hope for.
