anyway the final stage of belos’ character is probably going to be the complete collapse of every lie he’s ever convinced himself of.
we saw beginnings of this in clouds on the horizon, where they make a point of showing belos’ nervousness and how badly he reacts to the thought that the human realm has changed, and then again towards the beginning of king’s tide when luz straight up tells him that no one hunts witches anymore and his drip is trash. it’s pretty clear that, to belos, the idea that the human realm has at all deviated from his idolized fantasy version of it is a Bad and Unacceptable thought that he’d rather just ignore. he doesn’t want to think anything’s changed and he refuses to think he’s changed, either. the man is literally a goo monster playing pretend with human skin and he still believes that he is a regular human. he gets violent towards luz and the collector when they tell him he’s changed because he cannot bring himself to consider the perfectly reasonable idea that they’re right.
and then we have the scenes in which gus pulls up his worst memories and belos calls hunter “caleb”, which are like a minute total combined and also i think the most important scenes Of All Time for belos’ character.
his rationalizations for the murder of his own brother are so flimsy that literally just thinking about the event itself is enough to make him flip his shit. he knows what he did was unforgiveable and he knows there was no real reason for it and he knows the grimwalkers are not caleb, will never be caleb, he’s been playing god with his brother’s body for centuries when he KNOWS that caleb is gone and he will never get him back. and then, right off the heels of belos finally being forced to confront what he’s done, we see him calling hunter “caleb”. he looks at hunter, the grimwalker that looks the most like caleb, the one now holding caleb’s palisman, and suddenly he doesn’t see hunter anymore. he’s watching caleb “betray” him again, and he doesn’t want to see because it’s forcing him to think about why caleb did it. he was never corrupted or lost or in need of a merciful death, he just wanted something different than philip and that was unacceptable.
and finally: the collector! belos thought he could use the collector and then throw them away when they weren’t useful to him anymore, just like he has for literally every single person he came across for the past 400 years. the man has been acting essentially consequence-free ever since he murdered caleb, and then the collector is freed and immediately shows him that the manipulation is not going to work anymore. for once in his life he is facing the consequences of his actions, both in the past and in the now.
what happens now that belos is a small pile of slime on a completely different earth? what happens now that he can’t deny that luz was right, that he isn’t even human anymore? that his home is a place unrecognizable to him? that the childish goals he’s built his life around are considered a joke? is he going to double down or is he finally going to have to realize that he is a joke? that everything he’s done was for literally nothing? that caleb died for nothing? that maybe, just maybe, he could have led a happy life had he not been so obsessed with his own warped sense of righteousness and revenge?
the walls in belos’ mind are going down and brother, they are going to go down hard.
tl;dr: the show is making a point of showing thatbelos’ worst fears and memories are actively being brought to the surface in ways he can’t rationalize. he finally has to face what he did to his brother and the fact that he’s in a form that can’t even pretend to be human anymore. this man is going to try desperately to hold on to anything he can before the walls come crumbling down and we get the third-act breakdown we’ve been waiting for.
