Just glue the braid into Nynaeve's hands NOW! Give the people what they want!! I have also thought about this and shared your concerns! I don't really know how it's going to be possible without words--even in the books, it's lots and lots of words. Like, will they flash some images and Perrin will have to say out loud what they mean so that the viewer gets the full gist? I'm just preparing myself for the wolf communication to be unsatisfying. Then it will be fine if it's unsatisfying and a pleasant surprise if they figure out something cool.
