--Ah, so they've finally done something with him in that regard?--

Well, he's at the "run off with a shady organization because their leader promised to tell him about his birth" stage with Satan actively and almost literally hanging on him, so I have hopes. If they don't pan out, at least Rin's unlocked a new, dangerous power he has to master and been given a chance to time travel to learn the secrets of his and Yukio's birth. And, while I know it doesn't excite you, I will eat up all time travel in any form. Plus new powers and some Rin-centric story again.
