Great Expectations
He lied.
He lied a lot about a lot of things, using he words and deeds to control, manipulate and suck people into his delusion of truth.
But this time he even lied to himself.
"They have no expectations of me."
But even he knew better.
Wilson, Cuddy, Foreman, Chase and Cameron; they all had great expectations.
Wilson expected him to be a friend.
Cuddy expected him to be a doctor.
Foreman expected him to be a leader.
Chase expected him to be his father.
Cameron expected him to be right.
Sometimes he was, for brief instances in his existance, but most of the time their expectations were too great.
He often wished they didn't have any expectations at all.
Then he couldn't be a disappointment to them.
He lived without expectations.
Without hope.
So that he wasn't a disappointment to himself.
That was how he survived.
