Black Bolt: Gets arrested, makes a cell buddy, breaks out, gets science'd on with Inhuman Super Gene results, wipes out half of the antagonist's strike force and learns how to benevolence.
Medusa: Gets haircut'd, changes her wardrobe, befriends a nerd, dodges the law and learns how not to be a queen bitch.
Karnak: Gets nerfed, falls in with some :420: farmers, bangs a hot chick, gets some of his powers back, dismantles a drug cartel and learns how not to be a complete tool.
Gorgon: Hangs with some surfer dudes, gets into some fights, has to bury one of his surfer dudes and learns of the benefits of having a brain.
Crystal: Gets her dog back, gets her dog run over, falls in with a blonde dude who's available after breaking up with a bitchy vet, gets said bitchy vet to treat her dog and will probably learn something next episode like how not to be a douche bimbo or something.
Lockjaw: Gets gassed, run over, and nursed back to health by this nice bitch. Learns that being CGI Doge is hard.
Maximus: Learns that unlocking his gimmick is hard. Harder than usurping a throne at least. But that's okay because he's still unlikeable like every other Mootian (not named Black Bolt; seriously, his emoting is his real mutant powers; the "Black Canary but stronger because he's a dude and that this isn't DC where wall shattering vocal cords don't even get you into the Justice League until the third pass at the earliest" powers are just a bonus).
Also they got the band back together by episode 3.
