Well Armand probably wouldn’t like you, if that makes you feel any better! I feel that he is essential to the series and he’s my best friend’s spirit animal so I have to defend him.

He has very specific reasons to have tension w/ Louis and Marius, you might not have gotten to that info yet 😉 Maybe you’ll change your mind about him when you get more of his background.
This is why I loved earlier canon so much more than the recent stuff, there were rich layers with characters like Armand. We first meet him in IWTV as the mysterious leader of the Theatre des Vampires, he’s unlike anyone else Louis has ever met and they are enthralled with eachother. Armand is as alluring as Lestat was to mortal!Louis, but in entirely different ways. The more we learn about Armand as we go on through canon, the more we find that he wasn’t simply a survivor of horrible crap that’s happened to him, he’s actively tried to improve his circumstances, he learns from experiences, he is a sponge for knowledge, he has major trust issues with alot of other characters, he’s got a great sense of humor but he’s also really bitter, he craves love but struggles with receiving it, just, ARMAND. SO MUCH MORE than meets the eye.
Anyway if you like Louis at all, ya gotta remember that Armand rescued him from being walled inside a coffin upside-down for eternity so… y’know… there’s that.

Keep in mind mortal!Louis suffered from claustrophobia, and still felt it as a vampire sometimes, so this would have been an even worse punishment for him.
