After the Royal Family of Inhumans is splintered by a military coup, they barely escape to Hawaii where their surprising interactions with the lush world and humanity around them may prove to not only save them, but Earth itself.
There is a scene where Maximus sexually harasses Medusa. Most of this scene is verbal, and he places a hand on her shoulder. It happens shortly after the dinner scene, while Medusa is alone outside the Quiet Room.
The series ends (SPOILERS)... with Attilan moving to Earth. None of the main cast dies, and it is presented as being a hopeful ending. However, their previous home is completely destroyed, and Maximus is left trapped in Attilan's bunker by Black Bolt. It's a bit subjective.
Not sure if this counts, but Maximus heavily manipulates and lies to several characters, and often blames his own actions on others around him, alongside telling some that their memories of certain events were incorrect.
There are a two scenes of characters eating but the chewing sounds aren't loud or exaggerated. These scenes happen soon after Medusa breaks into the house, and after Medusa and Louise escape from the motel, for anyone who would prefer to skip them.
It's not explicitly stated, but Black Bolt has flashbacks and gets visibly upset at the mention of his parents deaths, and anytime he uses his vocal powers. Medusa also has a very strong emotional reaction to her hair being shaved, and remains visibly upset at mentions or reminders of it throughout the show.
Several parents are mentioned as being dead throughout the series, and Black Bolt and Maximus' parents have a death scene that is shown multiple times in flashbacks.
During the intro, Maximus has a nightmare, in which he appears visibly panicked and is hyperventilating. Not technically an anxiety attack, but may be worth skipping.
Several unnamed characters die throughout the season. Gorgon, one of the only black characters and the only black main character, does die in episode 6, but he is revived in the following episode.
In episode one, there is a scene near the title sequence where Medusa and Black Bolt are naked in bed together. There are no explicit sex scenes in the season.
Lockjaw is hit by a four wheeler at the very end of the episode, though it is a very quick sequence and Lockjaw makes a full recovery without any visible injuries at any point.
