So, Apparently: Voltron
So, apparently, while writing my Kiki’s Delivery Service crossover AU, I decided that I have a headcanon for how Pidge got their name.
Being competitive siblings who aspired to be in the same field, Matt and Katie Holt had several faux-condescending nicknames for one another. Matt was especially fond of Bird Brain when they were growing up, but Katie retaliated by listing all the bird species who were almost as intelligent or actually as intelligent as humans on some level. Matt, annoyed with her perfectionism, settled for calling her by the name of a very specific bird species. One nobody considered all that intelligent. And thus, the name Pigeon Brain was born. This name eventually devolved into the shorter, quicker Pidge. It was what Matt called her and nobody else, and so when she infiltrated the Garrison, it was only natural that she’d think of it as the best fake name to keep her undetected.
