- Franchise Original Sin: Some of the major events that most polarized the fandom in Seasons 6 and 7, including Buffy and Spike hooking up in a relationship and Willow's witch powers spiraling out of control following her relationship ending, are (coincidentally or not) foreshadowed, to the point of the whole episode seeming Harsher in Hindsight. Heck, it even brought Amy back! (Albeit for only two seconds on-screen.)
- "Funny Aneurysm" Moment:
- Xander asks to be blind along with Giles after watching Spike and Buffy kiss. This becomes less funny in season seven.
- After Willow's spell-gone-awry is broken, Buffy jokingly tells her that "we may be into a forgetting spell later". Loses its funny after season six, where Willow repeatedly uses magic to erase Tara's memories.
- Hilarious in Hindsight/Harsher in Hindsight: Depending on your point of view. The episode was largely made in response to the Buffy/Spike shippers, to point out how ridiculous a relationship between them would be. Less than a year later, the show bowed to the pressure and began to move toward pairing them up for real.
