I'm imagining it as a movie now. There would be a special, dramatic, full orchestral leit motif that plays when people speak ideals!
When someone starts to speak an ideal, but fails, it stops suddenly on a discord.
When...a certain someone who I won't name in case of spoilers...speaks the words in Oathbringer...perhaps the leit motif could be played quietly on a guitar instead ...
My favourite moment was after reading the poisoning scene in Book 1 (or 2??), Then I went to bed. And I woke up half an hour later going "OH CRAP!" because I realised that all was not as it appeared. I wasn't entirely right about what had happened, but I was desperate to pick up the book again!
