Does anyone else find that this is a tip of the hat to Buffy the Vampire Slayer? I mean, come on, of all the names in the world they choose Buffy for the lead vampire. If not, than some writer doesn't know his/her television history. I think this is an obvious nod that the sneaking writers added to see if anyone would run up the red flag and go, "hey, Buffy!" Tricky, tricky. And the fact that the episode stars one of the former cast of Buffy, James Marsters, who played Sunnydale's resident "Big Bad" Spike, makes it even more delicious. Plus, several former staff members of Buffy now work on the Smallville staff (eg- Steven S. DeKnight). I'm just saying this must be an ode to Buffy or a major mix of coincidences.
