"In B:TVS Seasons 1-3, there is an establishing shot of three girls talking next to a fountain in the school courtyard (the one standing up has short dark hair and is wearing a yellow jacket). This shot got reused so many times that it broke my willing suspension of disbelief every time I saw it. Then, while rewatching “Homecoming” today, it occurred to me: Sunnydale High is on a Hellmouth. There must be some kind of time loop bubble thingy going on that nobody has ever noticed, and those poor girls have been stuck having the same conversation over. And over. And over. Again. For at least THREE YEARS."
