I'm glad you like it. [he considers for a moment, playing a couple notes on the piano] It's a shame you haven't had the opportunity to see an opera, considering your enthusiasm...

[he tilts his head a bit, giving Orpheus an almost conspiratorial smile]

I'll tell you what. I don't think I could get an entire opera done anytime soon, but I could flesh out and finish this scene. Perhaps there are some singers and performers among us, and we could stage it, at least? Then you will have seen at least part of it.
