Tell me about it. He did a short run on Supergirl (I think that was in '04?) and vanished after that. I asked Damion Scott last year if he ever talks to him given the two were tied at the hip in Batgirl and Batman. He hasn't heard from him either and not since awhile. Damn shame... I be curious to know his perspective and if he ever have more tales to tell of Cassandra.
Sounds like a hell of a scoop of you track him down
Last mention I could find was 2 issues of Ninja Scroll for Wildstorm in 2006. Maybe he's in whatever basement Didio has locked away story drafts of every character Herald cherishes.
Still hard to believe that the character of the first ever Batman title who sustained it for years got buried in favor of a character most infamously well known for the Alicia Silverstone role. I know Harass has a 90's hard-on bigger than Draco's but to go that far?
