Events of We Happy Few Edit
After Arthur enters through the two doors next to Dr. Harold Ridgwell's office, he gets ambushed by Dr. Oldershaw and knocks him out, straps him to a chair in a test room and get forcibly induced with an early test of Coconut Joy.
When testing Arthur with the Joy, they find that it doesn't work as well as they had hoped, and therefor lets him go into his cell. Though, because of a malfunction, their room explodes and Arthur is able to escape through the broken glass.
- It's possible that one of the Doctors shown testing the Downer in 'The ABC's of Happiness' trailer is Doctor Oldershaw.
