Hi, do you think that in 378, Sera intervened on purpose at that specific time so that John wouldn't end up killing someone and that causing him to spiral?
Hi! Short answer: yes.
Very long answer: Yeah, but also I also think that if Sera knew that John was going to be heavily injured, she would've rushed to help him sooner. But considering that she came to help not too long after Valorian was taken hostage, there is a good chance that she was watching them fight and waited until she had an opportunity to act. I do also think that Sera must've taken the time to head back to the motel to grab two of the disablers to use on Scorch and Cinder, but it probably only delayed her slightly in coming to assist John.
In episode 377, she didn't really seem all too worried about how John was faring on his own because she knew he wouldn't be struggling with using his ability. She assumed John would've been fine against those EMBER agents, so she wasn't rushing to go help him. On the other hand, you can see how worried she is for him in ep 379 as she tears down the road to get him healed as soon as possible.
She definitely didn't foresee John taking so much damage against Scorch and Cinder because if she had, she would've intervened much sooner and taken them out before they would've had the chance to hurt John even more. Neither of them are in a position to be letting the other act recklessly, especially now that they're in the real world away from Wellston, the protection of their friends, and support from Darren (which John points out in episode 380).
While John has definitely grown as a person since the start of the series, you can still see that some bad habits of his persist even up to this point in the series. In this case, John is still looking for excuses to hurt other people, but he is able to better justify his ruthlessness against EMBER and the authorities. All because they're horrible people upholding a corrupt system that only benefits a select group of the power-hungry.
Unlike his senseless violence streak pre-season 2 part 2, John actually has a valid reason to go after the authorities and EMBER: they ruined the lives of everyone he knows, especially his family's, Sera's, and his own. Sera's absence in that turbulent part of John's life lead him to almost throw his life away in an attempt to take down as many feds as he could (though it's unknown if he actually managed to kill anyone... I'm sure Uru would've mentioned it in the story by now if John actually killed a bunch of people). She wasn't there to actually stop him from losing himself, and John had made a deliberate choice to not "bother" her with more "unneeded" stress.
Old habits really do die hard... The most unfortunate part of that arc is that Sera definitely would've risked getting caught if it meant she could support John when he really needed her the most. But John chose not to seek Sera for reassurance and it led him spiraling once more (though he does notably treat his friends a lot better since the last time his mental health took a nosedive).
Obviously in episode 346, we see that hearing about John's self-destructive behavior ended up adding to Sera's stress greatly, and I doubt she is going to be willing to peel away from him any time soon, knowing full well that she remains his tether to sanity while he still grieves William's death. So now that John is within her reach once again, Sera is back to watching over John and upholding that promise she made to him way back in episode 230:
((Side note: Uru-chan makes it very clear that the main characters of unOrdinary are deliberately choosing a less violent way of solving their societal issues, in which I mean that the children are NOT killing anyone in their quest to make their world a better place. Kuyo and Blysenmi nearly kill Byron (Kuyo cuts down Arnold and that lady in ep. 333), Arlo and Blysenmi almost kill Farrah, and John and friends blow up a bunch of feds many times. Yet no one in the main cast has killed anyone as of the time I am currently writing this post (June 1, 2026). I'm glad that no one has actually killed anyone so far considering that our protagonists are 17-18 year old children who really shouldn't be desensitized to murder in a world already filled with so much violence. I enjoy that the children have more empathy to spare than the adults running around killing people without giving a fuck.))
Okay, back to John vs Scorch + Cinder fight:
With Sera's constant consideration of John and his needs in mind, I do think that she chose to give John an "out" when it came to dealing with Scorch and Cinder. John has every reason to be enraged at EMBER and the authorities, and Sera knows this as well. He brutalizes Cinder the most because she was within reach, and I know he would've done the same to Scorch if he was the one to get baited instead during the fight in episode 377. I really do think John meant what he said when he stated that he didn't care if Valorian got killed or not because it would've given him an excuse to kill both Scorch and Cinder. Considering he already broke Cinder's arms and shattered a bunch of her ribs (and did considerable damage to Scorch before Cinder got involved), I'd say this John is fully capable of killing people.
Sera intervening and giving John a disabler to use lets him remain "innocent" in the way that he wouldn't be haunted by the fact that he had taken lives during one of the worst periods of his life. The fact that John is an 18 year old teenager means that anything rash he does now would definitely end up weighing on him when he hopefully mellows out and his brain finishes developing. Sera is now around to pull John out of making extremely violent and rash decisions, so that's exactly what she does. Sera would never kill anyone, so she obviously wouldn't want John killing anyone either, no matter how angry and vindicated he'd feel after the fact. Wanting the best for someone is natural when you love them after all.
While I don't think Scorch and Cinder necessarily "got off easy" since they're now disabled and in Spectre's hands, they deserve every horrible thing that's bound to happen to them. After all, they did endanger a bunch of innocent civilian lives for the sole purpose of luring out and killing Valorian, who is also probably also a child or a young adult at most. If they can stomach killing children and innocent people, then they can stomach being lab rats or repenting for their actions that led them up to this point of their lives.
Judging from Leilah's reaction, you can tell that Sera and John both probably didn't think about the aftermath of protecting Eastbrook Town. Sera could only come up with the most convenient solution that would both spare John from becoming a murderer and ensure the two of them wouldn't be in danger after capturing Cinder and Scorch. It's an imperfect plan since Sera does dump the responsibility of dealing with Cinder and Scorch onto Leilah, but in Sera's defense, she is also a kid who sometimes will act rashly if it's in her current best interest (which is prioritizing John's wishes and well-being).
John does calm down very quickly after he disables Cinder, which does show that the development John's been having since season 2 part 1 ended continues to show the fruits of his and Sera's labor. The old John probably would've tried to kill Scorch and Cinder even if Sera tried to stop him, but our current John does a better job at listening to Sera and remaining rational despite the circumstances. I am proud of him!
Will Sera continue to try her best to be John's moral compass while keeping them both safe? I'd hope so! Even now she's still worrying about him because she feels responsible to keep steering him in the right direction, which includes telling him that he needs to ask Cameron for advice since he's vulnerable against EMBER agents and can't copy Time Manipulation.
It's not like John is incapable of thinking for himself either, but his grief will keep looming over him and temporarily blinding him from being rational when his emotions get the best of him. He still very much relies on Sera to keep him from losing himself, and it's nice to see that he does value her support--even if it's not explicitly shown in the story! Let's just hope Jera can make it out of this current arc in one piece ;w;
