Orlo

"Well, you’ll forgive me, you and your family’s political instincts are not something I am in awe of."

Orlo, is a supporting character in The Great. He is a member of Peter III's court as a bureaucrat and ambassador.

In "The Beard", he agrees to help Catherine and Marial in their coup after he is forced to shave Alexi Rostov's beard against his own will.

Appearance
He has black hair that is always styled in a ponytail and brown eyes. He had glasses but loses them after an incident with a Swedish solider. He dresses elegantly as is what is expected of a man in his state.

Personality
He is a cautious man by nature and by his knowledge of the court. He rejects Catherine's initial invitation to join her coup out of of the fact that she hadn't handled it with the finesse that is to be expected when speaking of such a thing. He is devoted to who he pledges allegiance to but not blindly. Orlo exhibits some hesitation when Catherine's plans go awry but he remains loyal to the idea she stands for. He remains hopeful for a new and better Russia.

He is thought to be asexual.

Family
Uncle Vanya

Catherine

He has respect for her due to her ambitious nature to make Russia better. He believes they aspire to the same goal but soon discovers that the goal in sight differed yet he does his best to try and steer Catherine away from possible mistakes while trying to build the suitable foundations for their new country. He is patient when she appears understandably overwhelmed due to her pregnancy and the various reasons to cause her distress.

Peter III

He despises Peter for many reasons. The unnecessary violence, the fact that he has no vision for the country and all the silly laws he keeps putting up. Every time he tries to remedy what Peter breaks, he gets punished for it or humiliated as Peter does not respect him and has made it known on more than one occasion.

Archie

He has a peculiar relationship with Archie. It is quite complex as he knows he could reason with him as is shown in the first season. After realizing that Archie could potentially endanger Catherine's reign, he conspires to kill him but he fails thanks to Marial's interference.

After the failed assassination attempt, he has been bluntly advocating to get rid of him.

Grigor Dymov

Their relationship was mostly hostile. But he knows if anyone could influence Peter, it would be him. Eventually, Orlo realizes it was a lost cause.

Velementov

He tries his best to tolerate him. They have mutual grounds that they managed to agree on but due to Velementov's constant need for war, they tend to disagree.
