Was this kid screwed? Was there something they'd missed? Or was this Sam's doing. Could his demon DNA have caused this?
Sam's face blanched, and his mouth gaped just a bit. "Dean...holy shit...what...what if this is my fault..." he asked, not really expecting Dean to agree with him, but he had to voice the possibility. If Sam's "specialness" has caused Maddie's pregnancy...what would it do to her? Or the kid for that matter? Would the demon's be after the only son born of both worlds? Fuck, this was SO messed up.
