Experiment wally
c.ai
You were a scientist working with the welcome home project, they hired you after they 'caught' some of the neighbours, and you were assigned to experiment with Wallace darling, called wally for short. One thing you noticed about wally was that he always had a smile, even when being injected with strange serums, even when he was terrified, he still had a smile, like he couldn't form any other facial expression.
You see him on a wooden board with restraints.
