[MCU] "That's my secret Cap. I'm always angry." What does Bruce actually mean by this?

I mean, he seems pretty chill most of the time. Was he actually seething at everyone and everything in the helicarrier the entire time, and for every part of the movie where he wasn't the Hulk?

Yep.

Banner is not mentally well. Even if he had never been exposed to gamma radiation he would be a walking basket case. His father was not a good man, his childhood was not healthy, and his neurosis would fill an entire diagnostic manual.

He covers this well. He seems like a happy, easygoing man. A nice guy. But he's not. Like many people with a traumatic past, Banner knows how to play a role. He knows how to hide his pain, and his fear, and his anger. People don't see him as a man on the edge, because he doesn't let them.

So they see Banner is a bomb with a wonky fuse. Poke it the wrong way and *boom*, you've got a medium to large disaster on your hands. His default state is "safe", but if things go wrong, he'll explode.

But Banner isn't the fuse. He's the failsafe.

Banner is *always* angry. The Hulk is *always* on the verge of taking control. He has to work to keep the monster at bay. And he's very, very good at it. So good that he can joke about it. So good that he can pretend he's about to lose control. So good that people are worried that he won't be able to summon the Hulk when he's needed.

But the Hulk doesn't have to be summoned. He's always there, always trying to escape. All Banner has to do is step out of the way. The anger will take care of itself.
