Wow! This was good! I confess that I'm not familiar with the Blood Ties universe, but the story swept along without my needing to know. Vampire fic usually leaves me cold (heh, I know, bad joke) but there's nothing cold in this encounter.
And I can just imagine the royally pissed off Joe back at the bar, pacing, waiting for Methos to show up after curfew. "You're so grounded."
