That's something I'd like to put in the game!
From the start of the game to the end of Build 0.5 it wasn't a very long time in-game and the MC + Asterion had some big fish to fry that kept them busy. Going forward, however, I think the MC as we have characterised him would suggest therapy to Asterion. Regardless of how good the MC is, Asterion is someone who absolutely, 100% should have therapy to help him unpack his emotional luggage.
The main question is how we'd put that in the game. Should it be a reward to R&D or should it be part of the main story? Should the therapist be a normal human or a mythical? How long should this content be?
Those are the real questions to me, because the basic premise of Asterion going to therapy is good.
Well, if anyone has suggestions for the how, feel free to drop them.
