The next morning, Jerome tells Calliope, "I'm really into you" (3.10.24).
She's all "I don't like you like that" (3.10.32), though, and he leaves.
The Object spends the day hanging out with Rex, and Calliope spends the day feeling alone.
That night, however, the Object crawls into bed with Calliope. Calliope pulls the sheets off her and kisses her; then she takes her underpants off. "The Object lifted her hips, very slightly, to make it easier for me. This was her only contribution" (3.10.48).
They spend each night like this: the Object pretending to be asleep while Calliope explores both of their bodies further.
Finally, they start exploring each other while they're awake.
Unfortunately, one day Jerome catches Calliope like Tom Thumb with his sister playing the role of the plum.
He calls them "Carpet munchers" (3.10.93) because he's classy.
Calliope attacks him and spits in his face, and then she runs.
In her tumult she runs right into a tractor, waking up later in the backseat of a car.
The farmer drives her to the emergency room.
When doctors remove Calliope's underwear to examine her, they discover that her sex is a lot more complicated than anyone ever suspected.
