Virtue and Wit

Luke could only grit his teeth.

He also cursed Tony Stark for his misfortune, even though he knew that Tony Stark wasn't really responsible for his situation.

He knew a thing or two about Tony Stark.

From the movies he had watched in his last life, he knew that Tony Stark had a unique personality, and that he could be a great hero, but perhaps not a great friend.

It was completely understandable that Obadiah, his bald uncle, would try to kill him.

Tony Stark called Obadiah uncle. Their bond couldn't be fake. Yet, the playboy couldn't stop himself from squandering his wealth.

It was in his nature, and was hard to change.

Thus, Luke never intended to make friends with Tony Stark, because it was too difficult.

It wasn't hard to imagine how haughty Stark was if he could shut the door on someone who had developed the ultimate virus.
