Spoilers: Full spoilers from Ending: Shackled

Woof, if any of the endings are about continuing themes established in the rest of Minotaur Hotel, it's this one: The redeemer takes on the shackles of those they have freed. Pretty accurate way to say this one ended up.

As mentioned before, we're given the identity of the realm's godly Overseer, the only god allowed access to the realm: Hermes. The big information we learn from him in this ending is that he has definitely set up the role of Foreman to turn into what it has: he is 'too busy' to actually oversee the realm (so the realms can conveniently go against the god's (Athena's) wishes) but the humans were getting 'too soft'. Thus he is forced to set up the role of Argos, but picks these big, flamboyant schemers that learned to try and be the villain so the Master can learn to maybe not be a dick. He needs his plausible deniability though, and he is mentioned to be the god of plots and schemes, so setting up this convoluted mess with the express intent that it (eventually) benefits Asterion is very in character. And as I mentioned before, it makes it a little more fucked up what Hermes is pulling in the Chapter 18 climax, throwing away his pawn of Argos/Nikos like that.

I think there's room for debate that Asterion might have intentionally doomed Nikos to literally take his shackles and punishment when he lashes out in anger in this ending just before he takes the Gift's freedom. It's impossible to know if the pelt would've hunted Nikos down anyway, had Asterion not said what he did at the end to Nikos, as the Dust and Silence alternate has them peace out before the pelt comes around.

Not really a spoiler from this route per se, but P finds it so funny that the cursed minotaur snake calls itself Argos, because P stands for Panoptes and he and his people 'should have' been the real Argos in a way.

Full spoilers from Ending: Dust and Silence alternate of Shackled

If Shackled is about taking on the shackles of the one they have redeemed no matter why or how you did it, this Dust and Silence alternate is the deliberate breaking of it through accepting it. Nikos is not just shackled by the realm as a punishment, but he instead calls this responsibility and joins Asterion through to his freedom to try and nurse his mental health back. Otherwise, no new revelations here I think.
