Spike remembers that full-moon. Hell, he stopped the other from making chow of the party goers. A few puffs of his cigarette though, as he debates answering that threat with one of his own or not.

"It's possible, but not bloody likely. Not with how it all went down." Spike grits out, sounding unhappy. "Look, I know I'm a monster alright? But she treated me like a man. I...can't think of how I'd stoop that low to her of all people. She already drives me crazy, and I was already set to kill her for good and proper once before. I didn't." Welp, that is one cigarette that didn't last long enough. Damnit.

Snuffing the tip out, before Spike drops it and grinds it into the dirt. "She died saving the world. Closing a rift between the dimensions, that was caused by the blood of her little sister. I already failed her once, and she had to do that to stop it. I don't want to imagine, and can't imagine, myself failing her again. Not like that."
