This is probably all over the place, but oh well.
Abolish is such an interesting character to me, like he has always been perceived as someone who’s in control, prepared and knows what they’re doing, even when the others are at the brink of a meltdown.
Even before he knew vampires existed (where we later find out he did know about them) he was very prepared, not willing to take a single risk of something happening.
He constantly overcompensated for everything, had enough silver to make sure he always would be safe and having garlic on him and growing in his garden. Even Avid the most paranoid person commented that Abolish’s was the most prepared person and that his house was the most vampire proof.
Another interesting fact about him is that as much as he keeps quiet and people not really knowing who he is, he has never lied to others. When asked about vampires he said he was open to it being a possibility, he truthfully answered why he was in Oakhurst. Sure he left some things out like the secret organization, but he never intentionally went out of his way to lie.
Speaking about going out of his way, that was also something he never bothered doing. He held everyone to the same standard, it didn’t matter if he didn’t trust them, if they were vampire or not. He talked to everyone normally, let them explain themselves, their reasoning and opinions. He in turned expressed his thoughts, if he was wary of something, if he saw something and so on.
Another thing about him is how it’s always been hinted that Abolish not your average man simply coming to greave. In the first episode he says he’s "used to do dirty work and getting his hands dirty." Followed by Ep. 7 where he insinuated that killing was a part of his work (during the confrontation with Owen about Avid’s death.)
Keeping himself in the background, watching and waiting to see if he had to step in. The only reason he did step in was because it began involving him and making him unable to leave the town.
That time he was doing everything to get the highest chance of leaving. Taking a step out of the shadows, but keeping his cards close to his chest. During his crashout he mentions that he "needs to get back into character." That was the Abolish that’s under his Oakhurst persona.
His persona is all about staying hidden, being underestimated and unnoticed, meaning he can’t be a threat or a target. His crashout happened alone with no one around so it wouldn’t become an obstacle to his goals and "calming down," getting back into his persona before going back into town.
When he explained his work we see a lot of his core elements he’s showing in the series. It explains why he’s indifferent to who’s a vampire or not, why he doesn’t go into the spotlight and why he always prepared for things that might not even happen "just to be on the safe side."
Now onto Owen’s and Abolish’s relationship. Throughout the story they have been relatively peaceful or passive towards each other. Choosing to talk before immediately jumping into a fight.
Also both being connected to Oakhurst, Owen by living there for the past 200+ years and Abolish having ancestors from there, there was one main theory which was:
Abolish being a descendent of Louis, Owen who would realize that would most likely help and defend Abolish. Though I really liked the fact that his ancestors most likely helped Louis and just barely missed his death and the slaughter of the entire village.
It was confirmed Oakhurst took place in the 1800s (by Leguneo), so Abilish still living in 2006, he should be dead at least 2-3 times. Also the half black and white hair with red eyes?!
He’s clearly not human, did could have been half vampire, which kinda makes sense to the story line.
Because his ancestors working close with vampires, maybe one got turned/ one married into the family and it’s just been in the gene. Not enough to become a full vampire, but to have some features of it.
It’s something he’s always had which is why he asked to get out of the disguise and why the old man didn’t seem surprised. It can als explain further why Abolish was so neutral towards vampires.
