I can't believe I forgot to bring this up until now, but another thing that really stood out to me was Danny's interaction with the child molester in "ReCycling." Stella was disdainful and disgusted by the man, as was Danny, but with Danny it seemed to be something more. Danny was angry. And, he personalized the encounter: Danny directly asked the guy, "What? Am I too old for you?" The first time I watched it, the line seemed odd to me, but now knowing all we know about Danny, it seems to fit in with the abuse theory.
Also, Danny was so hostile to the molester that the guy asked, "Does he have to be here?" Notice he didn't react that way to Stella, who wasn't exactly being kind to him. But, she was being professional and not making the encounter personal. The child molester also looked at Danny and Stella differently; I found the way he regarded Danny downright creepy. Danny almost seemed to be daring the guy to look at him, from the hip-badge flash, to the comment he made about being too old, to wiping the sugar-design off the table and leaning in. He also went one step further than Stella in telling the guy he was going to call his parole officer. For whatever reason, the situation seemed personal for Danny.
What do you guys think?
