I mentioned this in another thread, and I couldbe spreading lies for all I know but here goes:
Ken had a "partner" that he was working with on all his lines. As the story so often goes, his partner got tired of living in Kens shadow, so he up and left, taking with him what he claims are his own creations. Kens former partner is the mastermind behind Johnston's Genetics, who have recently appeared on the scene.....
Again all shit I've read on various forums. So take that with a grain of salt.
