Taking things up a couple of pay grades here, Jo...
As for Jo's references, she's taking us all the way back to our 8th storyline, "Under Hill," when she talks about everything starting with Alban and Toch. Of course, Scratch didn't actually show up in the comic till our 11th storyline, "The Apprentice," but he's been hovering in the background since our 4th storyline, "Dust Bunny." So much history!
