I'm looking for any stories where Dean uses sign language, either because he's deaf, mute/silent, or simply communicates with another character who is.

I've read a few with this theme already;
Silent Hunter - deaf!dean
But Deadly verse - mute!dean
There are a couple others I know of with silent!dean as a child, and one short piece where he talks to someone they save using it, but I can't remember where they are at the moment.

Anyway, anymore stories like this?
