When Spike and Anya fight in the Bronze, Anya throws Spike onto the pool table and the front panel of the table falls off, revealing pale wood. In the next shot of Spike on the table, the original dark panel has been replaced.

The heels on Buffy’s boots change at the end of the episode Chosen. When she runs up the stairs to escape the destroyed hellmouth, the boots have high heels but when she jumps off the bus at the end of the episode, they’re much lower. Only Buffy would change her …

Anya’s song ‘Mrs’ is sung in Selfless. The lyrics are:

Mr. Xander Harris. That’s what he is to the world outside.
That’s the name he carries with pride.
I’m just lately Anya.
Not very much to the world, I know.
All these years with nothing to show.
I’ve boned a troll, I’ve …

Anya wears her wedding dress from Hell’s Bells in her musical-based flashback in Selfless, implying that she brought her wedding dress long before her wedding day in season six.

In Selfless, we see a flashback to a night that obviously is intended to have taken place during the musical Once More, With Feeling, on the first night that everyone began singing. Anya asks Xander if the coconut thing was weird. In the musical she told the gang, “We were …

The 1905 scene set in St. Petersburg in Selfless was originally supposed to be set during the Renaissance but it was changed as the time frame clashed with the fact that Halfrek was supposed to be Spike’s first crush Cecily at that time (seen in Fool For Love).

Sarah Michelle Gellar was only available for three days to film the episode Selfless as she was getting married to Freddie Prinze Jr. that week. Drew Goddard said in his commentary for the episode that Sarah’s hair in the show (the little braid at the side of her head) was …

We learn in Selfless that Anya’s name as a human was Aud. She came from Sjornjost, and became a vengeance demon in 880 A.D. after turning her cheating boyfriend Olaf into a troll. D’Hoffryn offered her the vengeance demon job and renamed her Anyanka.

Principal Robin Wood reveals to Buffy in Help that he grew up in Beverly Hills. He also lived in New York, which is discovered later in season seven.

Principal Wood originally said in Lessons that Buffy would work two or three days per week. In Help we see that she has she worked at least four days in a week, but she had a tough case so I guess that fits in. Buffy’s office hours are 10:00 a.m. …

On Tara’s headstone, seen in the episode Help, her date of death is shown as May 7, 2002, the date that Seeing Red aired. Her birthdate is shown as October 16, 1980. This puts her birthday about three weeks before Family, the season five episode showing Tara’s 20th birthday aired. …

Buffy doesn’t seem to lock her doors. In Same Time, Same Place, Willow just walks into Buffy’s house through the back door whilst Buffy is out. In a place like Sunnydale, you’d be more careful. Vampires need an invite but burgler’s don’t!

In Same Time, Same Place, Xander comments that the blueprints for the school basement have become useless, as it seems like the walls move. This is probably the doing of the Hellmouth.

In an episode of The Bill (shown on 25th November 2003) a picture of Gnarl, the demon in Same Time, Same Place, appeared on a locker. The Bill is a long-running UK police drama series.

In Same Time, Same Place, Willow and Anya perform the same demon-finding locator spell that Willow and Tara did in Goodbye, Iowa.
