Indy was named after Indiana Jones who was inspired in part by the old Republic Serials like Commando Cody: Sky Marshall of the Universe and their ilk which I loved watching on TV growing up. Cody was named Cody when I got him, it’s a nice name, two syllables perfect for the dog to remember. So it’s a retrospective rewriting of history to link his name in memory of Indy. It satisfies my sense of whimsy . Although I’m pretty sure Cody thinks his name is either No, Come or Leave at the moment.
