Diminishing Returns

We've covered Iron Man, Doctor Strange, Thor, Thor: The Dark World, Thor: Ragnarok, the Captain America trilogy, Spider-Man: Homecoming and Guardians of the Galaxy volumes 1 and 2. Time to bring it all together in this delightful team-up episode. (Yeah, we know. We've still got The Incredible Hulk, Iron Man 2 and 3, Ant-Man and Black Panther to deal with. That's phase 2).
