So after Maximus tried to have the entire Inhumans family killed off, and may have succeeded in erasing a couple of main characters, Black Dolt may finally have a plan to return to Attillan and regain his throne.
So Medusa (Serinda Swan) flips her character and now is fighting for the rights of Maximus (Iwan Rheon), because if the Inhumans get revenge on them, then they are nothing more than... INHUMANS!
This episode sucked so much on every level of human interaction that it was painful to watch. All the discussions the characters had about Justice and Vengeance have been done a million times before, in a million better stories than this one. This TV series would have been much better if they had spent less time talking about it, and just gone back to Attillan and let everything play out without ten discussions about what might happen.
All the discussions and arguments killed any tension, suspense, or interest in the last episode. The characters talked it to death, and made it incredibly ponderous and boring.
