"There is," he says to the demon, "a way to travel between worlds without being summoned. I will trade you the knowledge of how to make it for three of them and some help identifying a habitable planet in our new dimension."
He is not remotely conflicted in that judgment. He has so much to do - and all the more traditionally relationship-like parts of their relationship are going reasonably nicely too, of course - there's just really something to be said for a boyfriend who will casually hand you huge difficult important world-spanning projects. He is flourishing.
But he recognizes that there's an argument to be made that some of the things that have happened between them are really bad signs, and he doesn't know where Kelora draws that line. Most people would see it as - well, non-trivial - that Maitimo implied an intention not to torture people into more convenient configurations and then tried to torture his Taliar into a more convenient configuration. Raika-seren is genuinely not bothered over it, but he has noticed that it is the sort of thing it would be reasonable to be bothered over.
