Wait a minute....
I was looking at my repost on @littleredandthebeowolf posts and i stop to think. COULD THEY ASK TO THE BLACKSMITH TO GIVE YANG HER ARM BACK ?!
She'd have to drink the tea first but yeah. The blacksmith could have taught Ruby how to use the silver eyes too.
Ruby knows how to use the silver eyes. She knows the headspace she needs and it only works around Grimm; there’s nothing more to teach.
Also, I think Yang has made peace with her new arm. It would feel weird to ascend just to say “Yeah, everything the same except I want a flesh arm again.” From an external perspective, it would very easily be seen as ‘curing’ her disability and would undercut her character growth of living and fighting without it.
