Nicholas Russo was very, very, very angry at Dimitri. His enemy had outsmarted him. He had promised to give Nicholas the business deal in exchange for Aurora's freedom, yet he did not anticipate that he had something else planned.
Dimitri always had a backup. Yes, he gave up that business deal, but in exchange, he hijacked two of Nicholas' ships, which delayed the manufacturing in his factories that lost him a ton of important deals.
He was hatching a plan to pay Dimitri back and make him suffer when the company doctor came to see him personally. But because everybody knew that Nicholas was frustrated and was having a bad day, they blocked him from entering.
The doctor was insistent, "I need to see him, and I am not leaving until I do."
But the PA would not budge, "Nicholas is very busy and has no time to see you right now. He will call you when he is not busy."
