[spoiler=And I can totally relate to him.] Thoughtful loner? Yeah, pretty much.

Observant, noticing the details other people usually overlook? Quite often.
"You're quiet and shy..." Exactly how I am in real life!
"...but once people get to know you, they understand your true worth." Maybe. [/spoiler]
