This is the first attempt to raise a vampire from the dead during the series; the first time it actually happens is in Angel: To Shanshu in L.A. (2000), when Wolfram & Hart bring back Darla. It is also the first time one of the Scooby Gang tortures a vampire for information.
Joyce and Hank Summers make references to the shoes of Los Angeles, while the bags apart. The LA shoes were also the subject of conversations between Cordelia and Buffy, both in the Unaired Buffy pilot and in Buffy the Vampire Slayer: Welcome to the Hellmouth (1997).
The following exchange was cut because of length: Hank: "Oh, I'm spoiling her. Did I forget to mention that?" Joyce: "What you forgot is that I'm gonna have to deal with another year of 'Daddy would let me buy that.'"
It may not have been intentional, but when Buffy is smashing the Master's bones near the end, one of the arms can be seen with all but the middle finger broken off, causing it to be as if the Master, even in death and being smashed, is shooting the bird at Buffy, forever telling her his feelings about their relationship and how she treats him. It can be seen several times during her bone smashing and is quite well aimed at her when she stops.
