After watching "Passion" I remembered, we haven't had an episode like this in such a long time in BTVS. The scene of Giles discovering Jenny's dead body breaks my heart so much. The last time we had a scene like that imo was in "The Body"
That's my favorite scene of all, but I think regarding the sadness-factor, nothing beats the death of a main character.I thought grave was a sad moment when Xander stops Willow from destroying the world. It breaks my heart every time I watch it. They have a beautiful friendship.
Even though this has nothing to do with this thread, I'd still like to share this thought I just had. Wouldn't it be hilarious if Spike said "I know." in that scene instead of "No, you don't [...]"? Like Han in Star Wars right before he gets sealed in carbonite. 😀[...]and the infamous phrase "No, you don't. But thanks for saying it."
