Am I nuts in thinking the title (and indeed plot points) in this ep refer to or at least echo lines from the Dingoes/4-Star Mary song Pain
? (Loaded up my gun/ there's a killer in me...)
I was rather hoping (from knowing the title and some of the subject matter in advance) that the Continuity Fairy might bless us with a reference to Oz in the Willow/Kennedy conversation in the Bronze. They did talk about romantic history after all, and it wouldn't have been out of plotline for Willow to say "I had a boyfriend before Tara, and I cared for him, but she opened my eyes to something much bigger, yadda yadda." And/or the song itself playing in the Bronze, with no more scripty acknowledgement than a smile or a wry look from Willow.
Not really complaining that it wasn't there -- I have far too many legitimate gripes with this ep to be so ridiculous as that. Just saying, would've been cool, and it seems like they missed out on something. Or thought of doing it and decided not to, mayhap.
