Spike drinks blood from a novelty mug which says ‘Kiss the Librarian’ in Something Blue and Hush.

In Something Blue, everyone says they’re sick of Willow’s constant moping about losing Oz. This seems a little unfair, especially on Buffy’s part considering she moped about Parker for a long time.

In Something Blue, Buffy and Willow still have the same recording on their answering machine that they did in The Harsh Light of Day.

In Pangs, Spike goes to the Scoobies for help after the Initiative chipped him. They tie him up and later question him as to what he knows about the Initiative (seen in Something Blue). Spike then lives with Giles for some time, and stays with Xander (Hush, Doomed) before moving …

In Pangs, the Scoobies leap on bicycles to go and help Buffy and Giles, which is a visual reference to the famous scenes from the movie E.T. when the kids ride their bikes to help E.T. the alien get back to his ship.

In Pangs, Riley mentions artist Grant Wood (1891-1942), who famously painted Iowa landscapes.

Xander’s construction work clothes in Pangs are described as “not at all Village People” by Buffy. The Village People are a camp band who dressed in various costumes, including a construction worker. They formed in the 1970s, and famously sang ‘Y.M.C.A.’ and ‘Macho Man’, which Buffy sang while under Catherine’s …

Xander’s bout of syphilis in Pangs is mentioned again in Once More, With Feeling when Anya sings, “His penis got diseases from a Chumash tribe” in the song ‘I’ll Never Tell’. In Buffy vs Dracula, Xander says that he’s is tired of being “the guy who gets the funny syphilis.”

In Pangs, Buffy says, “And Xander always tries to avoid all of his family gatherings.” We saw this for the first time in Amends, when Xander slept outside at Christmas to avoid his family’s arguments.

In Pangs, Xander is working for a construction company, a job he eventually finds his ‘niche in’ though he has a few more crappy jobs before returning to the trade in season five.

In Pangs, Angel returns to Sunnydale for the first time since Graduation Day (Part 2).

Willow’s views on Thanksgiving (seen in Pangs) seem to come directly from her mother, Sheila, who we met in Gingerbread. Buffy even says, “Okay. Now for some of that you were channeling your mother?”

We discover in Pangs that Riley is from a farm outside of Huxley, Iowa.

Joyce spends Thanksgiving in Illinois with Buffy’s Aunt Arlene in the episode Pangs. Kristine Sutherland, who played Joyce, was actually living in Italy for a great deal of season four which is why she’s conveniently not in the episode.

Buffy wears a black stetson hat at the beginning of Pangs. This is most likely a joke about “Cowboys and Indians”, the morals of which is the hot topic of discussion between the Scoobies in the episode.
