The dress shop, April Fool, in which Buffy admires the wedding dress in the window, is the same one in which Cordelia Chase worked in The Prom (1999).
Both Buffy and Giles are unable to see how Willow is truly feeling. Spike is able to see it right away. This perceptiveness is later exploited by Spike in The Yoko Factor (2000).
Shows Spike to be left handed.
Buffy and Spike's wedding plans were featured in the book "The Official Grimoire - A Magickal History of Sunnydale".
This line from Buffy was cut: "So she did a good spell - but the plan kind of sucked. I mean, she's the one stuck eating pellets out of a plastic cup."
