20 Past MCU Easter Eggs That Will Mean Something In Phase 3

20. "I'm Always Angry" (The Avengers)

The "I'm always angry" line uttered by Bruce Banner, prior to his controlled transformation in to the Hulk in the Avengers movie, was a major source of debate. "If he could control his anger, why did he transform involuntarily and attack Black Widow earlier in the movie?" Fans asked this questions in their droves and its fairly simple answer is that he was exposed to trauma and can't control his transformations under those circumstances. The fact that he is always angry, therefore, means he could be triggered at any moment and makes him a major potential threat to all of the heroes in the Marvel Cinematic Universe - and they will come to realise that in Phase 3. That makes that line extremely important in the long run. Expect the Hulk to be sent in to space in the third stage of the franchise in order to set up a Planet Hulk movie in Phase 4.
