Boromir looks relieved, for a moment. "Thank the Valor for that. A city as large as this one, and so few defences." That last comment has something of a scoffing tone to it.

He regards the being before him, unsure what the protocol is here. She's not an elf; there is probably not another creature like her in his world. He remembers the Halflings tales about their journey to Rivendell, of things he had only heard of in stories as a young boy. Finally, he settles on a slight bow and, "Thank you, river-daughter." Then turns to go.
