Mute Dadsona AU where Amanda of course knows sign language and makes it her goal in life to teach the kids at the cul de sac the basics, at least, so they can understand her dad.
Craig used to be fluent but he’s gotten a little rusty over time so he needs some practice but that’s fine! He and MC probably also have a lot of made up or secret signs only they know. He also helps his kids practice what Amanda shows them.
Hugo has learned the basics plus some more complex stuff just from dealing with dadsona and Amanda at school. Ernest acts like he doesn’t care but he and Lucien probably practice it together and are surprisingly good at it.
Damien immediately orders books and guides and dives right into learning more and ends up becoming near fluent faster than Craig can relearn it. Lucien is kinda along for the ride but he kinda likes using it like a secret code at school with Ernest and Amanda. Damien surprises Dadsona with his knowledge by bringing over a bouquet in person and signing he explanation for each flower. Dadsona cries a little.
Brian kinda struggles with picking it up but he’s okay with it because Daisy picked it up so quickly and she’s usually around when Dadsona is so he relies on his little girl for a translator until he can figure out more. He and Dadsona still have competitions though…
Mat gets nervous that he rambles too much around Dadsona since MC can’t stop him or speak over him. The first sign he learns is probably “it’s okay” just because MC uses it so much… Carmensita isn’t really the best at actually doing the signs but she can “read” them pretty well.
Robert I want to be fluent. Like maybe his wife was deaf or mute or a close family member was and so he is entirely fluent with sign language and so is Val and Amanda and Dadsona love that but Robert cannot be trusted as a translator. Someone will ask what Dadsona signed and Robert tells them that the MC killed someone and he needs them to drive him to the state border. MC then punches Robert’s arm, Robert giggles, then he gives the correct translation.
Joseph has no freaking idea what they mean for the longest time, he’s so busy with the kids and church events he hardly has time to stop and learn, but when he has the time he’ll look stuff up and he’ll stop MC or Amanda on the road to ask for a few phrases so he’s learning! The kids mostly don’t know it and Amanda is a liiiiiittle scared to teach them…
Mary learns through trial and error during nights out with MC and Robert and just guesses until she gets it right. Her guesses are more and more ridiculous as she drinks more and it makes Dadsona both exasperated while also holding back cackles. Mary secret learns some other phrases by watching Joseph and Damien and Robert.
