His adopted father died, although he did not know that he was adopted at the time. His real father, Zoltron Carpathien, is a sculptor. Was going to be Alicia godfather, but backed out at the last minute. Has dated Karen Wilder, Karen Antonivoch (who died), and Maricella.
He was a brain surgeon. Then he had a brain aneurysm and was left unable to operate, (4-3) but recently picked up a scalpel when a patient was dying and he was the only doctor around (4-24).
