Anne Pratt survived

In season 7 we learn Spike turned his mother into a vampire they had a small struggle and she was staked. What if during that struggle instead of being staked she was able to knock him side and fled into the night. Spike traumatized by it buried it deep down never turned another vampire. Now 100 plus years later in Sunnydale she turns up now she's a master vampire who's got one hell of a reputation as being a brutal killer. How would this affect Spike and the others? How would Buffy view him learning that he turned his sick mother into a vampire to try to save her given the recent loss her own mother?

Preferably season 5 My favorite season

I'd like to see a deep character dive into Spike. He's still traumatized by what he did but he knows he can't save her or himself. I think this would be a very emotional thing for him and I think that the Scooby Gang witnessing it could really change how they view the world.

No cans or have nots here just a story idea I had.
