[Willow sighs. It's horrifying, of course. Most of what John does is, at the very least, mildly horrifying. Clearly, he's convinced that destroying the world was the only possible route to take, and she doesn't think anything she can say will convince him otherwise.]

How is there even still a fight now? The world was destroyed, and if there's no one left to remember it... who's still fighting?

[She draws a deep breath. The world ending through more mundane means, she's not sure she would have a solution for anyway. Nuclear weapons and floods are a little outside of her usual wheelhouse.]

Yeah, I guess I have to admit it. I'm not sure what we'd do if it was a less... supernatural type of apocalypse?
