Danny likes to joke the Steve has an ego the size of the moon, and while Steve is fully ready to act the part, smug and smooth and right, it’s the fact he actually doesn’t that ends up getting to all of them.
Steve does the job because it’s the right thing to do. He breaks the rules because it’s how to get to the victims and criminals fastest. He does it because he’s been doing it so long it’s the only thing he really knows how to do entirely correctly.
Save the world, even if he can’t save himself.
