As much as I like this series and enjoy every chapter, it sometimes feels like all the other characters are made too dumb just to make Lily appear more wise and sound with her words and reasoning. If you consider the present company, it's made of the highest class of people among humans and elves, grand mages, nobles, royals, yet their rationality is weirdly impaired and their communication ability oddly limited. We do know Leonard is kind of an Asperger's case, but the others shouldn't surely be. I suppose this is the easiest way to give Lily an important role seeing how the story deprived her of all of the usual bonuses a reincarnator/summoned person would have, but I wouldn't sometimes mind more subtlety. That being said, the little squirt Jill actually is quite smart.
