Original Commentary

As that bottle gets emptier and emptier, Sofia's face gets redder and redder. For those of you who haven't read Unlike Minerva, Caleb always called Brisbane "Spike". The way Caleb saw it, it fit him better - Terrence and Isabel

Modern Commentary
The nickname "Spike" was pretty much the last remnant of Brisbane and Sofia being hedgehogs. Jack Benny's old bandleader, Phil Harris, used to call him "Jackson" so I figured Caleb ought to have a similar nickname for Brisbane. It's halfway between affectionate and derogatory. Like, Caleb isn't calling Brisbane that to be mean but he's not going to stop even if you ask.

I'm sure that Brisbane and Kimberly have mentioned Richard and Sinclair to Sofia, and Sofia was at least kinda paying attention. But they're not really top-of-her-mind right now.- Terrence
