Arya Stark wargs a ton (aka goes into the body of an animal) during "A Dance with Dragons," but we don't see any of this in seasons five, six and seven (so far).
Remember when she was blind in the books and show? Well, during "A Dance with Dragons" she can slip into the skin of an alley cat. It was really helpful to her in the book, letting her spy on other people while she was blind. She also dreamt through her wolf, Nymeria, a small sign of warging.
