"I apologize for the lack of introductions to begin, but I am Aragorn, son of Arathorn. I am from Middle Earth, but about sixty years in your future." It was still a strange thing to say out loud to someone, despite having spoken to Bilbo, Fili, and Kili here. He also didn't bother to explain how he'd was alive sixty years ago, but simply hadn't been in the same area as the others.
"Bilbo speaks highly of you. I had hoped I would be able to run into you sometimes soon." He knew it would have been eventual considering the size of Madison, but it was nice it happened sooner rather than later.
