Compound 0918 isn’t half bad.
Before going in for the tests, Dean had heard all sorts of rumors about the inside. He’d heard shit about people living in cells and being forced to eat, drink, sleep, piss, and shit under supervision, and to be completely honest, it had kinda scared him. He’d gone in anyway, because one, he didn’t really have a choice unless he wanted to run away, and two, if he really did have the right genes or whatever, then that meant Sammy could get away with not having to go.
Yeah, things have gotten better in the last couple o’ decades. According to the history books, there wasn’t that whole sibling protection clause, where if one sibling was chosen, no others from that family had to be tested anymore.
Supposedly, the government has a heart.
In reality, the lead scientists behind all the testing discovered that the genetic link really didn’t matter; it was the compatibility, or something. So after that, siblings were declared off the hook.
And now that Dean’s on the inside, Sam is safe. Dean hangs onto that knowledge, because it helps him sleep at night.
