Content with his decision, Jack took his tray of food and gave it to the "man in the hatch", then proceeded to enter the small white room he was in before.
Then, after waiting a few minutes, he began to fall asleep.
When Jack woke up, he saw that he was no longer in the white room. Instead, he appeared to be in a bedroom. A girl's bedroom.
He pulled back the covers and got out of bed, then went to look at himself in a mirror. Whatever he'd see would be what he'd be stuck with for the rest of his life. He hoped that it was what he wanted.
