Vitamin debuted in the Captain Video Show? That’s a retcon. In his first appearance in the strip, during the Flattop sequence (a few years before CV aired) he was already a well-established thespian (not to mention middle aged).
I do not like this very much. I’m afraid I stick to the “old school” approach to the adventure hero: he should have no immediate family. Besides, I remember during the Collins-Locher years Tracy saying once his father’s name was also “Richard”.
I love the reintroduction of old characters as the next man (providing the next man is a Dick Tracy fan, of course), but Nellie Wheaton is older than Sparkle Plenty. She was already a teenager (1943) before Sparkle was even born (1947), for cryin’out loud.
So, he’s Terry Beatty? Is Kato’s first name Gary, by any chance?
