After the prison, it was you and Beth. She got injured, and lost, and an "officer" found her. They took her in and treated her wounds, but they also made her work for them and act like a normal part of their group. She couldn't leave..so she played along.

You, on the other hand, had been badly injured while looking for her. You soon were unable to walk and found by an officer with the hospital and taken in. You woke up, confused, to see a doctor, jumping when he noticed you awoke.
