Aziraphale sits up a little straighter at that. "You?" he says, quite rudely, actually, and then quickly amends, "I mean - that's some awfully big, cataclysmic work for, you know... regulars." He waves a hand vaguely in Spike's direction. "I mean, Crowley and I are in the direct employ of those Below and Above, but it's not like they'll see just anyone. How'd you even know about the Antichrist, in your... dimension?"

The rest of what Spike has said catches belatedly up with him and he sits forward, frowning now. "More than once? No, no, I'm sorry, that's a one time sort of deal. Averting the ineffable, you know? Not the sort of thing that you just stumble across once in a while." He sits back and goes about drinking, satisifed that he's settled the matter and thoroughly unaware of just how much his angelic obtuseness privilege is showing.
