I am fairly certain Ryan is a functioning alcoholic. That's why he goes out with his buddies. If you're drinking with a group at a bar, it is more acceptable that drinking regularly at home. Plus, he just LOVED to hear himself talk..and talk.....and talk.
Molly was cold as ice and calculating. I believe Jon recorded her because if he had tried to tell people how verbally cruel she was, she would have denied it and said he misinterpreted things and was twisting her words.
