We may not have Lucifer in my world, but we do have ancient, unkillable immortals. Aside from my family, I mean. He's called Silas, and apparently he's a jerk.
Your husband won't care if my family dies. I don't blame you for putting him first, I'd put Stefan first. But since Sam pretty much hates my family anyway, I don't see him really giving any sort of crap if Lucifer did kill all four of us along with Crowley.
