A very old elf, and one that has enough patience when it comes to children he likely would not have taken offence at any such questions. Which might be apparent in how willing he is at awnsering the boys questions. "The sun and moon are merely the third light sources to brighten the world were I come from. When I was young there were two trees that did so, though they only lit one small part of the world."

"I mourn the loss of those trees, for they were truly a thing of beauty... but it would have been a tragedy as well if the sun never rose, I suppose. It would have been unfair to leave the rest of the world in darkness, I think." Which makes him wonder why the Valar never tried to do something to light the rest of it before the trees died.
