Tony sees that reaction and realizes the faux pas even before the elf is pointing it out. Ah, right, most elves wouldn't actually have such a high opinion of Feanor as Tony did. That had actually been pretty stupid of him to say.

For once, he accepts the fact he made the error and apologizes. "I'm sorry, you're right. I have found some tendencies of the train to pull people from their world and time connected to someone else already here. A number of Feanor's immediate family are here and I was aware he had a number of children. Elves are also not a known besides folktales from where I'm from."
