About the Louis/Armand scenes in 3x07:
First of all, I said this about 3 times already, but again: they are both monsters. They solve their issues in a monstrous way.
And it's not even as horrible as what some humans do to each other.
So, for the scene: yes, the body horror was exactly that, body horror. You could call that unnecessary, otoh it was simply practical. That may sound cynical, but it is what it is. Armand needed Louis immobilized for his confrontation and Lestat out of the picture, otherwise it wouldn't have worked out.
Since those two absolutely did not take him seriously.
Yes Armand is completely fucked up. As are a lot of vampires. But in interaction with other vampires who stregth-wise are somewhat equal or at least close to his level he could have gotten basic respect.
Both Louis and Lestat though thought he was too pathetic for that.
And Armand is caught between his need to somehow rectify that disrespect and his need for actual connection.
His way of finding whatever counts as closure for him was to confront Louis in a way where Louis had to react.
And Louis does not want to play that game at first. So he refuses.
Which drives Armand to extremer measures.
To Regina, the one human and actual victim in that scene. As a non vampire she could not withstabd Armand's manipulation and was in a vulnerable position. So she played along.
And got severely traumatized and almost killed for it. That was the one part I found unnecessary. I don't think Claudia needed to be brought back that way and I don't think Regina needed to be dragged into that shitshow.
But emotionally, she served as a strong visual representation of Louis' guilt and regret. Him seemingly cooperating when Armand threatened to kill her just showed that Louis still didn't get over Claudia and never will.
As a quick side note, I do love how Armand decides who lives and dies. Some 'mindless' follower gets offed without a thought. Regina, who was smart and interesting gets to live, but with a warning.
Now to Louis seemingly cooperating. Yes, he was not honest at first, of course, he was forced to play along by extreme measures.
But in the end he decided to switch to openness and honesty.
Maybe because he thought 'fuck it, might as well before I choke' or because it also meant closure for himself in regards to his relationship with Armand or because he thought Armand should finally get some closure himself.
So Louis apologized for the only thing he was responsible for: staying in a loveless relationship. He also acknowleded Armand's trauma from his past human life, which nobody ever did before and took responsibility for using kniwledge of that trauma to emotionally control Armand.
Because he did, in combination with their Dom/Sub relationship.
So yes, Armand built the 'relationship' on a lie. He did it out of desperation, but that is no excuse. He also fucked with Louis and manipulated his memories to keep him.
Also horrible and totally on him.
But Louis started the relationship, despite not being in love with Armand. He could have walked (ok, as soon as he was able too) away after the trial. But he instead stayed with Armand. At first as a fuck you to Lestat. That was very clear in the tower scene. Louis doesn't feel anything during that kiss. It is a demonstration to Lestat how little Lestat seemingly means to him.
Louis then proceeds to treat Armand as a doormat, he pity fucked him without any genuine care and outright ignored him, pushed him away and insulted him.
He fucked (ad drained) -what was it?- 138 dudes? and let Armand clean up the mess.
While cosplaying the happy rich hipster gay marriage for his own fucked up reasons.
That certainly caused another crack in Armand's already fractured psyche.
They both abused each other.
And now Armand forced his closure (which also served as closure for Louis, at least in regards to Arman) and got it.
And he was satisfied with it.
He let Regina go, he let Louis and Lestat go and simply fucked off.
And I consider that a happy ending. For a gothic horror show. I've seen and read way worse.
I don't disregard Louis' trauma btw, but he had two whole seasons of focus. Lestat had one season. Armand can get one scene.
Because, to get back to the start, they're equally montrous, and every monster deserves their own coping strategy.
