Arkham Asylum Doctors

Arkham Asylum had a great deal of staff members working on the island, many of who were working on the night of the Joker's takeover. Others, like Thomas Elliot, weren't present at the time. It is presumed that most staff members (that is, those who survived the events of Arkham Asylum) lost their job when the asylum was closed during the events of Akham City. Some, however, got to work on the medical team (i.e. Aaron Cash).
