fake prophecy, fake buffy post chosen fic

Hi!
Cannot recal what fanfic it was but, I remember the real Buffy running away and ending up in the glorida keys? The whistler retrives her to get spike in rome where he and angel and the immortal are arguing on a prophecy. There is a fake buffy with memories from the real buffy. Then the real buffy and soike get it on in the vents.
Anything like this ringing a bell

This is definitely With All My Heart by spikeslovebite which can be found on Elysian Fields. As soon as you mentioned Spuffy sex in the air vents, knew exactly which story it is cause I can't forget them falling through the ceiling.

that would be the one!
Thanks!
