Oh lord, I don't even think I would feel guilty reading fic where they were involved. The internet has clearly ruined me. Besides, I would be interested in seeing Danny give up his life of crime for her or something. (What can I say? Clichés are a little charming.)

According to Wikipedia (and also to the information we covered in one of my psychology classes), pedophilia is sexual attraction to prepubescent children. So, David wanting to be involved with Jenny is definitely creepy, and he definitely fetishizes the age difference, but it's not pedophilia.

(Also, I love your icon!)
