Just curious.
For me, it’s in Season 6 when everyone gets amnesia due to WIllow’s spell forgetfulness spell oopsie. Once they undo the spell and everyone’s standing around, Xander chuckles and says “I just back the memory of watching King Ralph.”
No idea why it’s THAT moment, but it sticks with me and always makes me smile.
When Spike is with Joyce in unburdening himself about Drusilla dumping him and Angel comes up and can’t get into the house. Joyce thinks Angel is still evil and Spike is just mocking him behind her back. And then of course the conclusion when Buffy grabs Spike and invites Angel in.
Love Joyce and Spike’s weird little friendship
