Mike seems the only sane one there to me tbh. Given all his problems he's not doing too bad I don't think.
Let's have a look at poor Mike. He hasn't been there that long; was the guy the Iowa left behind to run a frikking nuclear power station; has to spend his time hiding from Trisha (probs!); probs has Marcus waving vitamin tablets at him every time he steps into the corridor; if he avoids the Jones then he can spend time with either Kelly or Amanda...(oh...joy...); has the MC turn up ignoring his advice (perhaps - your mileage can vary); does his best to keep the lights and power going tries to be friendly and cheerful with everyone he meets!
And what does he get? Snark.
Even Sarah has a go at him. Poor Mike...
