Re: Becky's
Lucifer would tell her its a matter of free will. You decide who you want to be and to Heaven with the rest! He's certainly willing to show her that immortality isn't so bad.
tbh, he'd let her bite him regardless of if she's a vampire or not because kinky. I think he's still got a night or two of sleeping in the coffin at the mortuary at that point but after that, I think that he would invite her over for a drink to his penthouse.
