In Doomed, Buffy says, “The last person I know that believed that is in a coma right now because she had so much fun on the job.” She’s talking about her nemesis Faith, who she stabbed in Graduation Day (Part 1).

We discover in Doomed that Riley is a Psychology graduate student, which means that he already has a Bachelor’s degree, and that he’s at least 21.

Forrest, played by Leonard Roberts, tells Riley in Doomed that he “don’t got game,” which is an in-joke because Leonard was in the 1998 movie He Got Game.

Marc Blucas was added to the opening credits as of the episode Doomed, an indicator to fans that his relationship with Buffy would be fairly long-term.

The ruins of Sunnydale High seen in Doomed were all computer generated.

A couple of new businesses in Sunnydale are seen in the main street in Hush: Sunnydale Securities Bank and Hank’s Jr. Mart (a liquor store).

The rhyme that the girl sings in Buffy’s dream at the start of Hush is sung to the tune of “Master of the House” from Les Miserables.

The episode Hush sees the introduction of the Buffy/Riley theme tune, written by Christophe Beck. Joss mentioned in his DVD commentary that he prefers the Buffy/Riley theme to the Buffy/Angel theme as it’s more mature.

The soda machine that Tara and Willow magically move in Hush is the same one that was used in Sunnydale High School in Go Fish and Halloween.

The scene in Hush where Xander and Spike wake up and can’t speak was directed by regular Buffy director David Solomon as Joss was to busy at the time to oversee it.

You may notice that, until the gang lose their voices in Hush, they talk a lot about speech and communication. This is the theme of the episode, in that when people stop talking, they start to communicate more, as language itself can be inhibiting. Joss Whedon said in his DVD …

Due to the wonders of technology (or the zoom button on my DVD remote) I’ve checked what Giles’ handwritten notes say in Hush. The rhyme which Buffy heard in her dream is written in large writing, but in pencil surrounding this there are notes such as, “Goosey Gander”, “Ring o’ …

The scenes of the Gentlemen gliding smoothly through Sunnydale in Hush were achieved by swinging them by wires across distances of over 120 feet using cherrypickers.

The Gentlemen were played by actors who had experience with mime or character work. Joss Whedon has said that a couple of the actors were practising their hand movements without make-up on (Joss had asked them to do ‘Nosferatu’ with their hands), and they were scary then so he know …

In his DVD commentary for Hush, Joss Whedon says how much Buffy’s blue sleeveless top (shown in the first scene) annoys him now, “It didn’t bother me at first,” he says, but he calls it her “Flintstone looking shirt”.
