How else does one celebrate the Day of the Dead but WITH the dead you love the most?  Dawn and Spike have a reconnection at Joyce’s grave.  Maybe Buffy will learn a few things by accidentally eavesdropping. 
Setting: S6 between “All the Way” and “Once More With Feeling”

“I know I’m a monster,” Spike said to Angel. “But ‘least I know how to treasure a beautiful thing. Not you. You destroy everything you touch, good, bad, and indifferent, everything you get your bloody hands on, from Drusilla, to your slayer, even to an ancient sodding treasure!” Spike confronts Angel after Angel destroys the Gem of Amara.

"Angel used to be my world," Buffy told Spike. "He turned me inside out, and when he left me, I felt like I was dying. I thought... if anything could make me feel alive, he could." Buffy tells Spike about her trip to see Angel at the end of Flooded. Takes place at the beginning of Life Serial.

“I played a stupid game with you last night," Buffy said. "I know I did. And I want to know why you didn’t try to do... what I think you probably could have done with me.” Buffy speaks to Spike after her drunken evening in the episode Life Serial.

After the Initiative is “shut down” a fatal decision is made that will change the face of the world and uproot everyone Buffy knows before placing her in the greatest jeopardy of her life.  A new world is born but is it one they would wish to live in? 

What if Buffy reacted differently to Willow's spell after Something Blue?
