Original Commentary
Peter, Caleb, and Goliath's last appearances, at least for a while. They showed up here because I like them enough to give them a proper send-off. But their world had to be torn down for Brisbane's story to go on.

Modern Commentary
Caleb was Brisbane's rival/antagonist. He was a talented performer who could do just about anything vaudeville-related and almost nothing else.
"Spike" was Caleb's nickname for Brisbane. I was directly inspired by Peanuts, where Charlie Brown was either "Charles", "Chuck", or "That round-headed kid", depending on who was talking to him.
There was a whole lot of Caleb lore that never really made it into the comic because there wasn't anybody who'd think to ask him about it - Terrence
