So, the episode 24 of Malevolent was a lot. I’m still trying to process how I feel about it. Is John – the eldritch being from beyond, a wayward piece of a god - becoming one of Arthur’s tethers to humanity, just like Arthur is one for him? Arthur definitely can’t find strength within himself right now.
Arthur seems unmoored. He lost sight of what he thought was right before. He’s ready to abandon people who ask for his help, this is the same man who – what, just a couple of days before? – was willing to risk his (and John’s) life and freedom just to bring some unknown prisoner water.
He’s all over the place, it’s painful to watch. He wants to keep himself and John safe, and he wants (to quote from TMA) “to get their murder on” and kill Larson. He wants to hold hands with John (it’s not a handshake, alright, man’s just repressed and probably didn't want to come off too clingy), and he is scared of the intensity of what he feels for John. It’s a lot. John killed his best friend and John IS his best friend, he doesn’t have anyone else. God, the way Arthur’s voice sounds at the end of part 23 when John returns, he was repeating John’s name like he was reaching for a lifeline, and here once again with the madness/love parallel from Arthur himself – I want to howl at the moon. (i keep thinking about Kayne’s choice of words “fall in like” regarding Arthur’s marriage and this love/madness thing that in-universe everyone and the king commented upon, Arthur, is this why it’s scares you so much, be honest)
He wants to compliment John, but he’s SO BAD at it he ends up throwing the word “monster” left and right, while desperately reassuring John that he, John, is not like that, he’s grown, he is a good person, he’s worth all the sacrifices Arthur made.
I don’t think its John’s “absence”, although Arthur probably wants to think so. The trauma is catching up to him – mainly the prison pit, but all the horrible things that keep piling up are catching up to him and he didn’t have time to process any of that.
