Can I ask about Glys and Tumi, which are Rlain and Renarin's spren. Obviously they have some weirdness from Sja-anat, but they seem very, very different from the other mistspren we see, whose name is Dreaming-though-Awake. And sometimes they seem like they talk like inkspren, with that focus on the "be" verb at the end of sentences, and things like that. Is there a reason why they are so very different - I mean we've only seen one other mistspren, but...
Yes, there are reasons indeed. I will give you more as the series progresses. Remember, Renarin has (right now) in the sequence book 7, and so you are going to have an entire Renarin book with its own flashback sequence that you can look forward too. It'll be Renarin in his thirties; he'll be older, he may be wiser. We'll see.
