It's hard, being the strongest man in the world.
For one thing, it seems to make everyone assume he's an idiot. And sure, he might not be his brother, but in his own roundabout way, Adam is actually quite intelligent. But he's also the oldest, pushed into responsibility. He resents it, acting childish almost out of spite. He hates that his strength, and Chase's smarts seem to put them at odds, but he strikes back when he's hurt.
He worries about everything.
He wishes he didn't, but it's his curse to care, that the strongest man has the biggest heart.
