This sounds like Gandalf when he tells off Pippin in the House of Elrond!

I believe there is some link between the Nazgul & their fear of fire in relation to Balrogs. Also, there is no harm with comparing the powers of the Nazgul with that of a Balrog, Melkor's greatest servants just behind Sauron.
