wishing isn't enough.

Growing up with your best friend, being nearly inseparable, doesn't mean, as you get older, you suddenly realize that you're possibly in love with him. That kills a friendship, if you're lucky. If you're not so lucky, you'll have to accept the fact that, once he knows, things will never go back to being the same between the two of you. Too bad Seamus was too optimistic to believe that. Besides, he'd just met Dean their sophomore year of school. If that's not enough to shake that superstition, then maybe saying that Seamus had a crush on Dean before they became friends would. Actually, it was a while before they actually became friends simply because Seamus couldn't manage to not embarrass himself or behave like an idiot around. And Dean, he never really paid it any attention, oddly enough. Sure, he noticed Seamus enough to think he was weird, at first; he most likely still finds him weird, but Seamus doesn't need to know that ...
The two hit if off well enough, enough to them carry on like they were attached at the hip -- at one point, at least. Maybe not that close, but Seamus was definitely the only person Dean would hang out with all the time, despite them being opposites. Dean was quiet and could go unnoticed at times, while Seamus was ... you couldn't quite say that you didn't know him. He was "out", as Dean called it, in more ways than one. Along with his bubbly personality, it was painfully obvious that he was gay. Though, that really didn't make any difference to his friends because they wouldn't have him any other way. The one flaw in Seamus' happily ever after plan was that Dean was rather secretive about his sexuality, but Seamus had often seen him talk to girls ... that and he'd never made a move on him. That meant he was straight, as disappointing as it was.
However, Seamus couldn't exactly be struck out on love. He just happens to find it, or at least something that made lead to it, in the most unlikely place, and person. Zach, short of Zacharias 'If-you-call-me-by-my-whole-name-you-die', just happens to meet Seamus early enough to kick him out of despair; really, he'd probably just want to kick him. They're more of opposites than Dean and Seamus were. Zach is considered a loner, with a select group of friends, who all have the same hobbies as she does: drugs, parties, and loud music. How Seamus managed to draw his attention, we'll never know.
