And, searched wiki about Riviera, it says 'incompetent'. So maybe, an insane doc. But, insane doc can also kill a person right?
I don't think he is insane doctor. I just think since he is cheap and as you mention incompetant. He can not do as good a job as Dr Hibbert. Which is why I think he can protect someone alternate nights unlike Doctor Hibbert who can do it every night.
I am pretty sure he will be able to protect someone tonight.
Anyways I am off to bed. I really can't make any more contributions than I already have.
Hoping for more discussions by other members of town.
