Since he was a small child, Joey had learned to conceal his desire to be female, so much so that wearing the mask had become automatic. So as he was led to the switching chamber, not an expression on his face showed his true feelings. He slid easily into an expression of hopeless, passive despair befitting someone who was seeing their life effectively ruined.
Beneath the stoic mask Joey wore was a surging feeling of "I'm gonna have tits! I'm gonna have a cunt! I'm gonna have ovaries! I'm gonna have a womb! I'm gonna be a mom! I can wear dresses! I can have my hair done! Goodbye, Y chromosome!"
As Joey's body drifted into unconsciousness, the attendant wondered why he was smiling.
