Buffy captured by the initiative

I'd like to find a fic I read some time ago where Buffy is captured by some left over bit of the initiative. Dawn does a spell to get Spike's chip out so that he can rescue Buffy and Spike gives Dawn something to knock her out so she won't get involved in the rescue. But Buffy (who has been given something to make her weak) thinks he is going to hurt her and Dawn so instead of being grateful she is trying to stake Spike.

I think this it.
