Hmm, you think so? I thought it was fairly believable since it was implied that their meetings had been going on for a long time, so, he had plenty of time to groom Danny into accepting all of it (and it showed via flashbacks that sitting on his lap/kissing? was the extent of their physical relationship I think? Unless I'm not remembering correctly) -- and he did seem like an extremely manipulative person-- the killer, I mean. Forgot his name. However I'm not sure if it was really even necessary to add the whole molestation element, seeing as the killer's personality issues/intensity coupled with their inappropriate friendship would have been quite enough to lead to the kid's death, I figure. I don't know! Maybe if the flashbacks went farther back into their history it would have felt a little more believable/natural.
