1 Work by queerer_kindness in Supernatural
Gabriel Novak and Simon Tam were friends through their families, and their school. Both of their siblings, Castiel and River, went to an advanced academy when they were fourteen. When they found out that there was something wrong, they worked together for two years to get their siblings out again. They finally managed it. So Gabriel and Simon boarded Serenity at Persephone, and ran away.
They ended up dealing with an angry captain, coldhearted Alliance, and savage Reavers. Not to mention everything in between. But at least they're still alive, right?
*Rated M because of implied torture with the Alliance academy thing and lots of language.
