I think the wolf thing is going to be hard to convey. That's one of those things that is so so so hard to translate from book to screen. I'm not sure what I'm more afraid of: that they'll just do words, or that they'll do images and it'll look cheesy and horrible.
The moment that Lan essentially barks that at Rand and he starts walking like that is a good example of a little thing I need.
Also, if we don't get some behind the scenes footage of Mat and the dagger whispering "my precious" I'll be really disappointed.
Honestly, because it was always repeated how the Seanchan slurred their words, I always imagined something closer to Parseltongue. :lol
Now it's Southern Russian Parseltongue. :rofl
No WONDER nobody can understand them.
