"Yep. Subway trains. You know, sub like 'below?' It's because the rails are under the streets, in the tunnels there." Yosuke explained. He didn't have a very thorough working knowledge of France, but he knew enough of it to assume that Eponine might be aware of the catacombs in Paris, and understand the concept of underground tunnels if not the trains that roar through them. Then again, maybe she wasn't, if she was from so long ago. It was hard for him to tell. Even if he'd known when she came from he could have only guessed. History had never quite managed to keep his attention in school.

"Tell me about Paris. I only know about the Eiffel tower-oh. But maybe you don't." He laughed a bit at the strange irony of that possibility, and shrugged. "Anyway, tell me about yourself."
