Spike driving across county?

So this has bugging me for days but I can't remember the main plot to this story just like one scene that I think is towards the very end of the story.

Spike is driving across the United States either talking to Buffy telepathically or at less on the phone. He'd been rewarded I think with the Shanshu or something like it but he appears where he "died" which which is the hellmouth or the LA alley. So he has to drive back to Buffy, who's in Cleveland? or at less somewhere cold.

Does this sound familiar to anyone?

There's a scene of them talking on the phone cross country in zennjenn's "Third Time's a Charm".
