What's the matter with Dawn, not wanting to talk to Spike now?
So that's the end of the flash backs - I hope they are ready now for the new big bad to come :)

Author's Response: She's upset because of how he seemed to care before and now he didn't tell her he was back. There will be more to it as well but that will come a little later. The big bad will show up shortly in one incarnation or another. thanks for sticking with all the backstory!
