In "Something Blue" Willow (still distraught after Oz's departure) and Buffy engage in the following exchange:
BUFFY: (answering phone) Hello? Uhh.. I'll be right there. (Hangs up) Spike escaped.
WILLOW: A-and you're going? Now?
BUFFY: Sorry - duty thing.
WILLOW: Well, I mean, what's the rush? Spike can't hurt anyone, right? And I figured since I'm kinda grievey, would could, uh..you know, have a girl's night. We could eat sundaes and watch Steel Magnolias and you can tell me how, at least I don't have diabetes.
BUFFY: Will, I can't hang out with you until I get Spike back to Giles, you know that. Okay, I'll be back as soon as I can. I promise.
