If you don't mind me asking about your janka reversal Au. In this au, since jabber is like 'the good guy' right. Mentored by Enjin. In a certain situations where maybe Rudo/Riyo/or anyone he close with in the cleaners were to seriously hurt by Zanka. What is Jabber reaction? Like even if Jabber were to have some sort of 'feeling' to Zanka.
Ooh I love this question! Jabber hides it a lot better in this AU, but he’s still very emotionally stunted in that he doesn’t quite… care about others in the same way a normal person does. While putting this AU together, I really wanted to explore how Zanka and Jabber would fare on the opposite side while still making it as consistent with their canon personalities as possible! So cleaner!Jabber harbors sentiments that are similar to canon!Jabber’s—he thinks that those who are weak (according to his standards) aren’t worth his attention and tends to treat them with condescension if he doesn’t outright ignore them. The people who he thinks are worth interacting with receive the brunt of his affections.
In canon, Jabber seems to be very motivated by pleasure (not that kind of pleasure). When he fights, not only does he get the adrenaline rush, but his dopamine levels go up. Dopamine is a hormone that is released in response to something rewarding, causing pleasure, excitement, and motivation. In Jabber’s case, it’s fighting people who are stronger than him, and also getting rewarded by Zodyl. It’s normally released in short bursts before returning to baseline. So if an individual experiences prolonged exposure to high dopamine levels, the brain naturally compensates by reducing the sensitivity of dopamine receptors. Thus, the person craves higher and higher levels of dopamine and continuously engages in pleasure-seeking activities. Except Jabber became too strong, and he couldn’t reliably get the same pleasure from fighting those weaker than himself, so he forcibly suppressed his strength and his Vital Instrument, just so he could struggle a little—so he can “fight and fight and fight, and never win.”
So anyway! My theory is that Jabber enjoys battle and by proxy the pain that comes with it because when he's at baseline, he’s in a state of anhedonia (inability to feel pleasure, which is linked to dopamine deficiency)—because he finds the simple act of existing to be understimulating, and the thrill of battle is the only thing that gives him pleasure. When he’s not fighting, he’s very subdued and relaxed, if not a little apathetic. He stabs Gris without even blinking. He pulls up late to an important mission because he’s “bad with directions” which I think isn’t necessarily true—he seemed to navigate Penta just fine! I think he just didn’t care enough to follow them properly at that time.
When Jabber is faced with the possibility of fighting a strong opponent, it’s like he comes to life. Even just the anticipation of battle causes a physical reaction—he salivates, he trembles, jumps around, bites his lip, etc. Pain is universally a noxious stimulus—you’d think that he’d grow to hate battles because they lead to pain, but it’s actually the opposite! I don’t think he likes pain by itself, but rather, he loves fighting so much that he’s grown to associate pain with the dopamine and adrenaline rush that battle gives him—therefore, pain and pleasure have become almost inextricably linked in his mind. That’s also why I think he likes poisoning himself, because it’s like a battle that occurs within his own body. The fact that he likes spicy foods suggests that even the very act of eating has to elicit some kind of pain response in order for him to enjoy it.
So circling back to Jabber’s capacity for caring about other people! He appears to lack empathy—actually, he tends to do the opposite of empathizing, which is projection. If apathy is a lack of interest/emotion and empathy is the ability to understand how others feel, projection is displacing one’s own feelings onto others—assuming that others feel the same as yourself. It’s a psychological defense mechanism deployed to avoid experiencing negative emotions to their fullest.
During his battle against Zanka, Jabber gets carried away and projects his own feelings onto him—he assumes that Zanka is also hiding, assumes that Zanka is also repressed, because to Jabber, repression is a great existential burden, and he’s desperate to find someone who is undergoing the same struggle, someone who can understand what he’s going through (ironically, someone who can empathize with him). When he sees Zanka laughing from his poison and looking like he’s having the time of his life, Jabber wants to feel the same happiness—his expectations brought him so much excitement, but now he’s suddenly back to feeling nothing. And these instances might seem like empathy, but they’re not, because he’s not really trying to see himself from Zanka’s perspective—he doesn’t know Zanka like that. But regardless, I think that Jabber thinks he’s genuinely “helping” Zanka by urging him to unleash the brutality hidden inside him. It’s his own way of caring—he thinks Zanka’s in existential pain and wants to relieve him of it.
I actually find it so interesting that when the anime showed him lying down next to Zanka, it almost looks like he’s forcing himself to laugh and my reaction was like “HOLY SHIT” because ever since my overthinking ass first read that part in the manga, I’ve wondered how much of Jabber’s laughter is genuine, or if he was trying to convince himself like: “Zanka’s laughing because he’s having fun, so if I laugh, I’ll also have fun and forget about all the nothing I feel right now. HAHAHAHAHA—omg Zanka we’re having so much fun right? RIGHT???”
(The Jabber characterization plus Zanka’s backstory plus the amazing art plus the devastating ending is why that fight is my favorite in Gachiakuta. Hands down. Also I actually haven’t watched the full fight yet because I’m patiently waiting for the dub—I just got spoiled on Twitter.)
So getting back on topic, cleaner!Jabber does care about other people—his version of caring is just different and he himself certainly doesn’t recognize it as such. Enjin, Riyo, and the rest of the cleaners have managed to (unintentionally) condition him so that being around people who care about him makes him feel good—it’s a very different kind of pleasure than what he associates with fights, but it feels good regardless, and because of that stable support system, because he’s used to having access to a steady supply of oxytocin (AKA the warm, fuzzy, social bonding hormone), his need for dopamine (battle and pain) isn’t quite as extreme as it is in canon, and his capacity to feel empathy for others is increased.
If Zanka were to seriously hurt Rudo (who Jabber hasn’t known for very long) in an active battle, Jabber’s first reaction would probably be, “Not cool! I’m gonna be in so much trouble!” And because Enjin and Arkha had drilled into him that the safety of others should be his first priority, he’s gonna pick him up and try to run away to assess his vital signs and make sure he doesn’t die.
However, if Zanka were to seriously hurt Riyo, who Jabber has known for longer and personally likes (I elaborated on Jabber’s relationship with Riyo here), Jabber would be like “Man, what the fuck!” Then he’ll carry her away to perform first aid. The difference is that in Rudo’s case, Jabber is operating on the understanding that other people don't respond to pain in the same way that he does, and their suffering is actually not a good thing from their point of view (yay, empathy!); but in Riyo’s case, Jabber will be more upset because seeing her suffer causes him distress—and if she dies, he’ll miss her terribly.
(I like the thought of Jabber actually wanting to stay with people who genuinely care about him instead of going off the deep end in the blind pursuit of strength.)
No matter how it happens and who it happens to, Jabber’s going to end up feeling slighted. He’s going to stand watch over their infirmary bed pouting and grumbling “It should’ve been me.” (But not in an angsty way. More like he’s seething that Zanka hurt someone and it wasn’t him, and he’s going to make him regret it.)
