What I really can't wait to see in season 2 is how they will handle the dynamic between Louis and Claudia after they kill Lestat.
Right now they are both using him as a recipient and scapegoat for all their tensions and frustrations. Disclaimer: I of course think he has behaved horribly and deserves everything that they will throw at him. However, looking at Louis and Claudia's personalities and interactions, I find it interesting that - in their obvious love for each other - in a twisted way they still need Lestat to function together.
When Claudia first realizes the actual consequences of her vampirism, she gets mad at both Louis and Lestat. She later forgives Louis because she deems him more deserving of her love. But I think the reason she is able to do that is also that she has a place where to put all her hate and anger cleanly and without remorse: Lestat.
Louis, on the other hand, hates himself terribly and always has. I am not saying that Lestat's recent actions didn't contribute to his unhappiness, but it's pretty clear that he has been inching towards depression and suicidal thoughts since before his turning. The only way he has found for dealing with his current brand of self-hatred without consuming himself completely is to turn almost every negative thing he feels about himself onto Lestat. Everything ugly and twisted and wrong in his life becomes Lestat's fault. The more he hates himself, the more resentful and violent he becomes towards Lestat. I am not surprised that the writers decided to place Louis' decision to kill Lestat at the end of his depressive spiral. Of course in part he is killing him to actually get rid of him. But I think it's pretty clear that subconsciounsly he is also hoping to kill the part of himself he hates.
Moreover, both of Louis and Claudia feel a sense of anger and despair at being so lost in the world and so alone, so isolated. Their humanness stripped away and no one of their kind to understand, apart from Lestat. He is their maker and this makes him almost a stand-in parent figure in context. Both Louis and Claudia are in the youth of their vampiric lives. And when we are young and facing the world for the first time and finding ourselves unprepared, what do we do but blame our parents? We blame them for their failures - that's true - but also for not being able to be the omniscient, omnipotent force we once believed. We blame them for the shattering of every illusion of safety we ever felt.
Just to clarify again, I fully believe that a lot of the blame Lestat is shouldering is deserved and stems from his own actions. But precisely for this reason, he has also become a very easy way for Louis and Claudia to not confront each other and themselves.
So, where will this leave Louis and Claudia when they are alone? When they have no one to blame anymore for every single thing that goes wrong in the world and between the two of them? I am super excited to find out.
