I thought Craig was the best of the bunch, but after this past season, that's not saying much. His lackadaisical attitude would drive any woman crazy, during that episode where his assistant came to his house and he's still in bed at 1pm, haven't opened any boxes or done stuff his assistant asked him to check on. Then his rage out of nowhere at Austen during Cameran's party where Austen had the audacity to go home at 11pm. And then all that Naomie said things that Craig called her in the past.
Like Shep, I think Craig is an alcoholic. His disdain for Metul not taking shots just because *gasp*, he has to wake up early the next day is a clear sign. He probably just manages or hides his alcoholism better than Shep.
Alcoholism, maybe? Not only it damages the liver, but the brain too, no? Isn't that where the term "raging alcoholic" came from?
I won't be surprised if it ends up that Shep not only needs an intervention or self-introspection soon, but rehab. He's getting there. He already got a liver scare, which didn't stop him from still drinking. But all that rage and attitude issues, combined with alcohol, nicotine and drugs, make for the perfect recipe.
