This is a series of vignettes, based around the dead time, between S5 and S6; post Buffy's death.
They're based on Spike's line from S6 "After Life":
"But I want you to know I did save you. Not when it counted, of course, but ... after that. Every night after that. I'd see it all again ... do something different. Faster or more clever, you know? Dozens of times, lots of different ways ... Every night I save you."
Spike talks in Season 6 "After Life" about Buffy being gone for 147 days, don't worry, I won't come up with that many different dreams, I don't think I could…
Disclaimer: don't own any of them wish I did, just like to toy with them in my own, weird ways.
Night Number 35
Spike climbed higher. He looked above him. The poorly constructed tower of steel creaked as he ran up the steps. He could see Doc's knife gleaming in the moonlight as the short, inhuman figure approached Dawn. Spike stopped to catch an unneeded breath and started running again. The steps never seemed to end; they just kept running up and up and up. Finally Spike reached the top of the tower. It was swaying with the wind. Buffy was fighting the small, lizard like man, Dawn's blood was dripping from her abdomen and wrists, tears ran down her cheeks. The portal was opening, evil trying to escape from the gargantuan tears beginning to form in their universe. Spike swung his fist and easily knocked Doc off the tower. Buffy smiled at him, and kissed him. Spike grabbed Buffy and bit into her neck. She understood what he was doing and held still as he pulled her closer and closer, attempting to get just enough blood, but still leaving her enough to get off of the faulty tower. Ripping himself away, still in game mask, he gently pushed both Dawn and Buffy towards the perilous stairs. He looked Buffy in the eyes one last time, whispered softly to her and took a running leap off the platform.
