Just look at his eyes. Look at them. Tell me this isn’t the face of a man who loves his team to literal death. The face of a man who would risk (and has) risked everything he has for this team, because he cares so much. Sure he’s snarky, matter of fact, and arrogant, but you can’t look me in the eyes and tell me that he isn’t suffering inside every single day.
He needs the Avengers.
He needs his friends.
He needs his family.
His family may have broke in Civil War. Just a habit for him, he grew up with a jerk father. But in Infinity War?
It was like losing his family all over again.
