"I didn't leave the complex for weeks well after you had gone. The only reason I'm upright at all is because Nat wouldn't give up on me. So I'm paying it forward." Because it's the right thing to do, yes, but more importantly to Steve because Thor is someone he cares about and is still here. Still alive.

Steve doesn't want to lose him, too.

"I'm not going to give up on you." He holds out a hand expectantly for Thor to take to help the god up to his feet. "Show me around. Please?"

That's three hundred and fourteen souls that want to see their king succeed. Who are relying on him to lead them through these horrible times. Steve can't do that for his friend, but he can sure as hell support the Asgardian.
