You are doing a fantastic job with the story. This chapter brought tears to my eyes. 

Buffy’s feelings are very realistic. As a slayer, she is not accustomed to being powerless. That combined with not knowing who did this to her puts her in a vulnerable state. When she feels that way, she goes into denial and suppresses her emotions, which usually explode in a violent way. 

I also like Spike’s awkwardness in dealing with Buffy.

You are taking on a frighteningly real subject of date rape and handling the aftermath with care, concern and striking emotional upheaval.  I can't even begin to imagine the victimization and helplessness.  Buffy, however strong physically, will have to work her way through this process of recovery of her sense of self and security. 

Interesting in the latter part of the fic that Spike is the one to limit her retribution on the vampire.  He shows concern, but he's not handling her with kid gloves.  He cares, but he doesn't attempt to comfort.  Will she find this to be helpful to not be coddled in the aftermath? 

I think that you've got the makings of a great fic in progress here.  Looking forward to your updates.   

I hope Spike finds the nerve to help Buffy - she's in dire need!
