[Private]
[He doesn't exactly make a face, but there's a definite flicker in his eyes at the order. But he's soldier enough to follow orders, especially when there's a good point about protecting other people behind them.]
Will do. And right after it's over, too. Whatever happens, I'm not likely to be out of it for long.
[Of course, there's always the possibility that Spike might manage to actually capture him and stop him being able to make that call (he is, after all, paticularly vulnerable to capture when he's dead) but he doesn't think that's Spike's style. And now, if he doesn't make the call, he'll have back-up anyway. It works for him.]
