"Mom? What the hell is going on?" Jon asked.
"Mom? Rick, do I look like your mother to you?" Jon's mother asked.
Why did she call him Rick? That was his father's name. Then realization came to him. Maybe she called him Rick because he was Rick. Jon slowly looked down at himself and nearly screamed when he realized that it was true. He had his father's body.
This must have had something to do with that vague wish he made the previous night. But if Jon was his father, what happened to his father? Was he Jon now?
