Troll? I think he's just a 13-15 year old kid with no life. He pops up everyday around the same time -- immediately after school I imagine -- and runs to his room to post madly on Freaks. His mother is probably aggravated when she calls him for dinner and he keeps yelling back "Mom, I'm doing something important!". Has he ever shown anything of his collection? Has he bought anything? He seems to always pass for some inane reason -- Stormtroopers aren't the same height. I'd really like to see his room.
I think he needs to get outside more, get some exercise, and some friends he can touch.
