LOL! I know he's for sure showing up -- this would be just after Duncan finds his empty grave -- in 1867. I just haven't decided how to, one, present him, because I don't think he's always stir crazy, but I'm not sure my interpretation would fly with readers, and two, if he reappears later on, in the 1920s, which was related to my opium pondering yesterday [g] (this is for 'I Am Going to the West' btw) I've only written Kronos in that one fic earlier this year, and that was an AU version, so I'm dithering :)
