new theory still waiting for approval
As a child, a young Brine lost a $20 bet, and instead of losing money. He did the unthinkable.
Prepubescent Brine injected heroin not in his bloodstream, not in his vein, but instead, the muscley part of his arm.
This had a devastating effect. He developed multiple anti-social disorders and had a mental condition called Sperg. He refuses medical checkups because he doesn't want his mom to know he did heroin at 10, so the mystery will always be spooky. That is, until his mother inevitably checks Brine's posts, on a Lego forum.
