What I love most about the finale is how it shows Louis finally on his own and content. Claudia calls him out for it multiple times, “who are you without me” who is Louis alone, because he never gets a chance to find out between his relationships to his family then lestat then Claudia then armand. Louis is always having to perform a role for those he loves and he has no idea who he is alone. The whole “yes maitre” roleplay with armand divorces him even further from who he is, forcing him back into the role of Louis the pimp.
But instead of going back to lestat Louis decides to be on his own, to fully be himself, and the redecorated apartment full of colour and pictures of Claudia and his brother is a beautiful expression of this.
