midnight museum

like the first couple episodes is like "oooo spooky museum, cursed artifacts, bit of monster of the week but like with cursed items, is Dome Katha's reincarnated brother?" and then the last episode is "Katha has become the new Christian God. the moon has literally exploded and is going to end the world. Dome is actually one of the 4 horseman of the apocalypse and shot down from the sky to take over a normal guy named Dome's life. Dome isn't Katha's brother, that's Chan, another horseman of the apocalypse, who is from a different universe and also looks the same as Dome because all celestial creatures look like Dome because God made them all look like that across universes and God is Katha but not really. Dome and Chan were both from different universes (there's currently 3) but were all mixed around because Death (who also looks like Dome) killed his God and destroyed his universe so he's been hopping around trying to find a new God also he's possessed the body of Adam (like from the Bible) who had become a mannequin." and they made that jump in like 10 episodes

Tor Thanapob as KHATHA and Gun Atthaphan as CHAN

It's Dome telling Khatha his imagined happy ending to their story, because there is no queer happy ending that doesn't include family and friends. Being alone with your partner forever is a sad existence that was only Khatha's imagined happy ending with Chan because he couldn't imagine anything better, because he had always been alone and the people in the village did not accept him.

See, with Chan it had to be just the two of them because Chan had to choose between Khatha and the village. But Dome doesn't have to choose, he's talking about people who care about both of them. He does say he will choose Khatha if he decides to stay, so I can't imagine why anyone would think Khatha is not more important to him than the rest, but it's not his ideal ending, and that's a good thing.
