Solution to communication problem in Transfer Error AU?
Sign language?
It’s possible Emmet and Ingo could have picked up sign language to either better help deaf passengers or if there’s situations where Ingo’s hollering isn’t feasible. Granted, it’s probably much harder to pull off with a few fingers missing, but Ingo’s a smart cookie. I bet he can figure out enough gestures to still communicate something.
He has exactly 2 “fingers” on each hand. I think that would leave only the broader gestures for him to use.
I don’t know enough sign to say for sure, but I think most require a lot of finger positioning to communicate, so only having 2 would be a HUGE hindrance.
