This is oldie, but goodie (not really, but who's counting). Starts out as Spike & Xander. Xander discovers a ritual that will bind him & Spike together, but they need help performing it. While researching the ritual, Angel & Wes decide to perform the binding as well. Giles is needed to help with the ritual & they decide they want Giles to be around forever too. Then it gets a little silly... And it ends with the fivesome's butler comic torturing Riley.
I *think* it was called 'A Ritual Noted' and I *thought* it was by a writer called Bronze, but I can't find it
Thanks & Happy Mother's Day in advance
Got an answer from Caliadragon; it used to be on Beyond Canon site before it got hacked. She's trying to get it uploaded again. Bummer it's gone, good it may be coming back....
