Remember how Kakashi said Jounins can usually use 2 elements, but Kakashi simply ignored Naruto's question about his second affinity? Like someone said before, this episode answers out question about affinity and technique usage. Potentially, Kakashi has one huge trump card that no one's ever seen. (Except maybe Guy and the 4th) I hope they didn't build this up for nothing.
