Sam and Dean Winchester have a tricky relationship with their parents. The boys lost their mom as youngsters, which threw their revenge-hungry father into the world of hunting. And by default, that meant Sam and Dean were thrown into the world of hunting, too.

Did we mention she’s back from the dead? Yeah, we told you it was complicated.
