#Crow fidgets in thief signs because I have a friend who does. I am bestowing upon them the highest honor of being immortalized in headcanon

Been chewing on the idea that some citizens of Satellite have a localized sign language. Like, think about it. Majority of the population's criminals, most everyone knows basic thief signs. Add on top of that the gestures a bunch of disparate gangs come up with, plus a way for people to subtly communicate even if enforcers are watching them. All Martha's kids have a pretty expansive sign vocabulary, both for when she needs to sign behind her back "There's an officer at the door" and just general home sign for talking quietly/to kids who don't verbalize well.

The POTENTIAL.

Yusei blaring loud music in the garage or having a nonverbal episode, able to communicate that's he's perfectly fine, just super focused on what he's working on. Crow fidgeting old thiefspell when he's nervous. Jack going a few years without practice and picking it up again secondhand as they start to teach Leo and Luna because he can't just admit he's forgotten a lot, that would be embarrassing, so he just huffily watches the twins practice and tries to commit it memory.

Satellite's got a lot of little codes and signals, a culture of saying "I'm here. We're different. We have each other." From the clothes to the culture to the language, and Yusei and Crow unapologetically refuse to give any of that up.
