In my last entry a few days ago I got a story where Xander gives Dean his IWC business card.  New I can't get out of my head the plot line of a story I read some time ago where the boys call the number on a business card, reaching Slayer Central (Cleveland or England), looking for info on the latest demon they're hunting.  After a few months and several phone calls Sam and Dean are invited to spend time in the chaos that is the Cleveland Slayer house...Xander, Willow, Andrew, Faith?, and several baby slayers.  I'm combing my way through Twisting the Hellmouth, but with almost 1300 SPN xovers split up into central character, then pairing or friendship, family or alternate 'verse, it's slow going.  (Three days and counting.)  ...help?
