As far I remember, at the end of the second movie Nava went after Niju, right? Well, this is the scene I had in mind: Niju being traumatized after almost drowning and losing his pack and Nava comforting him. Obviously, I don't think he would just start crying out of nowhere.. I think he would first play tough, maybe snarl or attempt to attack, but then softening and breaking. After the ''emotional'' scene, I'd like to think that the old wolf took Niju under his wing, gave him another chance and teached him how to rule properly :)
