"Sarah Michelle Gellar remembers me and I want her to know that I remember every moment of shooting that episode, as brief as it was," added Pascal. "She was such a kind scene partner and we had the best time."

Last year, Gellar celebrated the milestone 25th anniversary of the show, which was a TV spinoff of the 1992 Joss Whedon movie of the same name, starring Kristy Swanson as Buffy.

"25 years ago today I had the honor to introduce the world to my version of Buffy Anne Summers. It was an uphill battle," she wrote in the caption. "A mid season replacement, on a new network based on a movie, that was by no means a giant success."
