For a long and possibly uncomfortable moment, the large dragon simply stares at Zuko and her anger. It doesn't seem to phase him very much. Finally, he shakes his head. "What you may find may not please you, yet perhaps confronting it will eventually bring you peace." Eventually. Maybe. "Onto my neck then, if you find yourself strong enough." There's a few places for Zuko to set herself- there's right behind Paarthurnax's skull where there are plenty of horns to grab hold of but there's also a decent place at the base of his neck.
