A lot of uncertainty
The doctor told Lily and her mother outside the room that her reaction was not unusual. And that it most likely occurred when operating on his head injuries. He wasn’t sure if it was because of his concussion. But when asked if John’s memory will ever return, he was unable to respond.
A long journey
Lily was heartbroken. Her own father no longer recognized her. She knew she shouldn’t take it personally, but she couldn’t help herself. He had no idea who she was, who her mother was, what happened to him, where he lived, or anything else! He didn’t know anything. And regaining his memory would be a hard journey.
