Where does Kaira take Armpit and Ginny and what do they do?

As Kaira ushers Armpit and Ginny backstage, she asks whether Armpit is Ginny's nurse, and she is embarrassed when he says he's just a friend, realizing that she made an assumption because Armpit was black. Kaira, who is also black, hands them over to a technician, who seats them behind the speakers and brings them drinks.
