Love the idea of Denny and Alan as Faith's newly-found dad and step-dad -- couldn't happen to a nicer couple, considering that they're likely to take all the weirdness of Faith's calling pretty much in stride (or forget all about it, in Denny's case -- bless him!).

There is only one response that can be given.

Denny Crane.

This. Is. Awesome. Honestly, words fail me in an attempt to describe my love for this story.
It would be awesome if you could continue or have a sequel, maybe have Shirley meet Denny's new daughter or have Alan hit on some minislayers at a holiday gathering or even see what happens if Faith met her 'step-brother' Donny (as he's played by Sarah Michelle Gellar's real life husband, maybe there could be some sexual tension between him and Buffy). Really the possibilities for sequels are endless with this one!
You really caught the insanity and joy that made Boston Legal so wonderful, well done!
