I feel like the popular interpretation that Athena turned Medusa into a monster to protect her was influenced by Ovid's retelling of the Caeneus story.
The leaked flight video, Ryan turning evil, Butcher going full psycho....in hindsight none of the previous season endings mattered. They were basically just cliffhangers.
At the end of Guardians of the Galaxy (2014), Ronan asks Star-Lord how he was able to hold the Power Stone, to which he answers: "You said it yourself, bitch. We're the Guardians of the Galaxy.", which still doesn't answer the question, and I don't get how the director missed that.
