Angel switches bodies with Spike in mid-S6

I think that this was just a short fic, possibly at Crypt of Fic? All I remember is that Angel was in Spike's body for a time in S6, and got a better sense of the Buffy/Spike relationship during. I think there may have also been some Buffy/Spike reconciliation, but I'm not positive about that.

(Oh, and to clarify in advance- it had to have been Spuffy, I didn't read Bangel back when I read this one. )

Found this myself (why does that always happen)?

The Switch (at allaboutspike dot tripod dot com). Much, much sillier than I remembered, but still a good read!
