Iirc he was supposed to be the same character, but then voyager would need to pay royalties to the tng writers every episode he was in

So… I drank. I boofed. I bribed men to cover the shenanagins of other men. I am an accessory to battering mailboxes. But the most damning thing of all… I think I can live with it.
