But does the tardis translate sign language? And if so, if a deaf person walked into the tardis, would everyone they see appear to be speaking sign language?

And if that is true, THEN WHAT IF SOMEONE IS TALKING WHILE THEY ARE DOING SOMETHING WITH THEIR HANDS?????

AND IF A SPEAKING COMPANION RAN INTO SOMEONE THAT SPEAKS SIGN LANGUAGE WOULD THEY APPEAR TO BE SPEAKING?????

I’m very frustrated by this question, as you can see.
I need to know the tardis’ position on sign languages RIGHT NOW.
