I've been trying to get him to watch since the school year started (Two months ago) but he declined. Finally he broke down and watched it when he saw a bit of the awesome brony community.
He's only seen the first two, but he went the whole day quoting from it, mentioning it, and loving me whenever he sees me. He hasn't seen Party of One, he hasn't read Cupcakes, and he doesn't go to Equestria Daily, so he's not a hardcore brony yet but what he's dabbed into so far he loves, and I hope he spends most of the weekend finishing season 1, maybe even dabbing into season 2?
It'll be a while and I'll be his mentor, but I do hope that he gets into EDaily and all that, so I can have someone to legitimately talk about it to outside of the computer room.
