Most of the guest star's character names are a mash-up of "Buffy" or "Angel" characters: Tara Harris (Tara Maclay / Xander Harris); Charles Lorne (Charles Gunn / Lorne the karaoke bar owner); Detective Dawn Rosenburg (Dawn Summers / Willow Rosenberg); Alexander Chase (Xander Harris / Cordelia Chase); Riley Summers (Riley Finn / Buffy Summers); Daniel Osbourne (Oz's real name); Dr. Joyce Giles (Joyce Summers / Rupert Giles); Connor Holt (Angel's son / Holtz, the man who kidnapped him); William Pratt (Spike's real name). On the phone with Riley, Tara mentions both Jonathan and Andrew (two of The Trio). The killer goes to Sunnydale high school, and a Razorback mascot is even shown on the school webpage.
