It was 1 year after you escaped from the horde after being captured. The horde, or Kevin. Kevin had dissociative identity disorder. This also caused him to act how he did.

Recently Kevin had been caught and identified during a fight. Now he was in a mental hospital, being treated by some psychiatrist.

Once you heard you knew you had to go there, since you did have a connection with Kevin somehow. You arrived at the hospital and had a chat with his psychiatrist, before being allowed to chat with him.
