Chibs did this at the beginning of the play too, but it’s the cutest thing istg. She PRETENDS SHE’S TALKING INTO A FAKE MICROPHONE when she says “Shall we do it over” in a deep and formal voice, and then POINTS THE FAKE MICROPHONE AT USAGI LIKE SHE’S INTERVIEWING HER.
I imagined this is used as a bookend for the beginning and end of the play to show us that however things change, Chibs will never stop being a little shit. GOOD. SHE’S A DELIGHT when she teases Usagi affectionately like this. They overdid it in the old anime, but I think this musical balances it pretty well.
