Yeah duh. Maybe he's playing with Dexter, trying to see if he snaps. I think it could really cause a problem when Dexter doesn't call the police over it. That's what a normal person would do, and Dexter isn't normal.

I definitely think they are building that storyline for next season. He seems a bit stalker-y, so I figure he has some agenda that is specific to Dexter, like he has some weird crush on him or he somehow knows who Dexter really is or something. He was really interesting in Dexter before we knew about the hand and before Dexter shot down his video game idea, so he definitely has some sort of agenda going on, but we won't find out about until next season, I guess.

They better incorporate it back into season 7 seeing as they spend a lot of time on it! I was kinda disappointed at the ending of the Dooms day killer too it seems like they built all that up for a lame ending...except when Deb finds out about Dexter but I hate the fact that shes in love with him that's weird and makes no sense. They grew up together! :p
