I'm looking for fics where the Scoobies appreciate Spike's presence and his talents or intelligence or the fact that he saved their lives many times and the Scoobies are like "The guy is over a century old ,he must be smart " followed by heartfelt apologies

While Buffy is gone Spike earns the respect of the Scoobies in Coming Through by hulettwyo. I don't want to give anything away but when she returns it's ten(?) years later and she's shocked at how things have changed.
