There was some story where Spike was tranformed into a human by Wolfram and Hart. he was able to be with Buffy, but then Wolfram and Hart wanted to use Dawn as the Key for something. Spike was turned again into a vampire, and as a fledgeling tried to protect Buffy and Dawn. Power got away from Dawn as some kind of whirlwind that attacked the people around her from Wolfram and Hart. Spike drank Dawn's blood and threw himself in to close it, and ended up in some world of only ice. He stayed there for an incredible amount of time, long enough that he was no longer a fledgling when he got out. He was starving because nothing to eat existed in the world, and the snow and ice built up around him so he couldn't move or even think. Finally, the portal spits Spike back out but he's in terrible shape from the starvation and being frozen.
That's the only Spike in an ice block thing I can think of, and I can't think of anything where Buffy actually had to enter a hell to find Spike and get him out. |
