Patient 62 appeared in Season 2, Episode 4 Amnesia.
While in a dream therapy session with Dr. Roberts in hopes of being cured of his arachnophobia, a short circuit occurs which causes 62 an extreme case of amnesia upon waking. He not only forgets his identity, but basic life knowledge such as social norms and simple objects such as spiders and bread. His wallet is charred in the electrical short, hindering the staff's efforts to identify him. The only clue they have is knowing that he is married, due to his wearing a

wedding ring.
