I've been wondering the same thing! I really feel they didn't give his character a proper exit either. And now that the show is ending on it's regular broadcast, I feel we may never know what happens with Caleb. I doubt Michael will sign on to the online version. And I also doubt many of the regulars will either. I can't see many of them doing it. Some of them have already signed up with the CBS soaps (can't say I blame them!). But it's such a shame a great character like Caleb gets pushed aside for a night of the living dead remake.
