After all of our business with the ancient world, it would be really nice to go back to Amaurot and visit the other Hythlodaeus. I'm sure he'd love to hear about it – what happened to Emet and Venat and his real self, and the events in Elpis. He presumably wouldn't have those memories since they were obscured at the point when Emet created him, but I'm sure he'd love to hear the story anyway.

Though that makes me wonder, if the memories are still there subconsciously, would there be a chance that pseudo-Hyth got them along with whatever else slipped out of Emet's mind into his creation?

Anyway. It would be a nice little sidequest if they added it.
