Medusa and Maximus soon have a heart-to-heart. Medusa, after all, has spent the last few episodes pleading with her family members to spare Maximus’ life, and now we find out why. In those halcyon days before his coup, Maximus and Medusa were apparently friends — more than that, she was his only friend. Maximus notes that but for her, he had nothing and no one. Medusa correctly deduces that this must have been why he was so eager to usurp the throne — so that he could finally be someone. When he refuses to compromise, however, Medusa takes away his last chance at that false self-meaning by destroying the last Terrigen crystal. I was wondering if this show was all building up to Maximus going through Terrigenesis again and thereby becoming Maximus the Mad, but that doesn’t seem to be in the cards.
Soon after, Medusa makes her pitch to the people of Attilan. She acknowledges her own revolutionary parents, who had a plan for a more equal future in Attilan, and admits that no one can be blamed for thinking Maximus was on the same page. But he clearly is not, as his reaction to Medusa’s speech shows. He’s not on the side of the people after all; as far as Maximus is concerned, if he can’t rule Attilan, no one else can either. His failsafe has now made the city so vulnerable that it must now be evacuated. Luckily, Attilan has its own version of Mother Willow from Pocahontas — a face in the wall that can transport people safely back to Earth, even more efficiently than Lockjaw! Everyone starts taking that route, except for Black Bolt, who still has some unfinished business.
Finally confronting his brother, Black Bolt learns Maximus manipulated him into killing their parents. The younger brother faked a royal decree saying Black Bolt needed to be lobotomized; when the heartbroken young prince asked his parents “why,” the power of his voice killed them. Maximus now admits they died for no reason but his own ambition, because he assumed Black Bolt’s reaction would have been to depart for Earth and leave him the crown.
Black Bolt takes his wife’s advice and doesn’t kill Maximus. Instead, he takes him to Attilan’s secure bunker, an outpost that predates the city itself and is therefore self-sustainable even without the dome that’s about to be compromised. There’s enough food and water inside to last lifetimes, so Black Bolt locks Maximus inside. Outside, he finally uses his voice. Uttering “goodbye brother,” the supersonic effect destroys the outer wall, caving it in and locking Maximus inside forever. As Black Bolt leaves to join his fellow Inhumans on Earth, Maximus utters to himself, “I am the king of Attilan.”
And so Inhumans ends, with all of the major characters now on Earth. I suspect this show will probably be forgotten in the greater MCU, though it would be kind of fun to check in on them at some point. In the meantime, I would recommend checking out some of Marvel’s several Inhumans comics, all of which are much smarter and entertaining than this show.
