The Big Bang Theory's Bernadette as a demon is something I didn't think I'd ever see in Stuart Fails to Save the Universe — but, now that I have, it somehow makes complete sense.

Last week's episode saw us meet her in a wizarding world but, in this week's entry we're swapping the magical action for something a little more One Flew Over the Cuckoo's Nest-coded.

But who, if anyone, really is crazy? And when does Stuart Fails to Save the Universe episode 4 arrive on HBO Max?
