This was not a satisfying episode. I need more insight.
When Robin was talking about his rehab stint, he said how they dug down deep inside him and brought a lot of things to light, but I was like, um, what things? His biggest challenge in life seemed to be that he was insecure about being a bit short. One would think doing great in school, becoming a success in an amazing dream job, making some good friends, marrying, and having kids you love might level out your self esteem. But then he got lonely when away from his family for a few days doing his dream job, so he had to drink to the point of losing everything. Whuh?
I was thinking, well, maybe he just likes to drink. I was an alcoholic and I get that. ...but then all of the footage of him drinking, he was the most miserable drunk ever. He just stared into space looking sullen, sat a picnic bench drinking warm beer, or fell all over the place. He never seemed to have any kind of high, relief, or even peaceful oblivion from it. It was weird. I couldn't figure him out. Maybe he has severe underlying depression that went untreated or something.
