Let me post the review I made on Serializd for Mr.Kill's 4th episod on here too.
Each time I think I caught up on the plot my theories get thrown in the bin. For a mystery/thriller show this is a compliment BTW.
I stay on my intuition that Nekros isn't only one person doing (at least logisticly speaking) but the actor playing this episode culprit really is talented because all our theories can takes roots from a scene where he doesn't even have lines ! Thank you to the person that didn't take this character as an opportunity to just insert another GMM cameo (they can be good ones but it's always risky to fall on some bad acting within this company).
I have to say that at some point I was ready to believe anything. I even thought there was some supernatural part to the story earlier on (I know there isn't). I truly believes that Kaye isn't an active part of the killing, he wrote Nekros some times ago from what I understood, when the wound was still fresh, why would he have waited to put his plan into action ?
Whether Nekros is a cult driven by only one revengefull psychopath manipulating other victims or this is a real organization with multiple ramifications (some killers being more efficient than others). I can't see it as only one person doing and some random copycat (see me being wrong again). I truly believe (and hope) that either way the master mind isn't one of the main characters.(It would be a too easy plot twist in my opinion) but I can get behind them (one of the girls or cops or even Off's character) being part of the organization as an informant for this possible "organisation". There has to be an informant anyway because how did this guy recognized Kaye?!
Also let's talk about DewTee's character in all this. I'm not a bromance detractor (Wu is literally my favorite show from 2026 up to date) but what the hell are they doing? While Wu is really a bromance to me (especially if you ignore the "bonus scenes" that aren't really part of the story) Kaye's and especially Phat's actions are wrost than NiranPete's. Like watching Mr.Kill really makes me see the difference and convinced me that Wu is indeed a full bromance 🥲 (this is crazy that another bromance show makes me feel that instead of some random BL). So there I said it KayePhat are wrost than NiranPete 🥹.
Anyway this was long but this show really hooked me. Let's see if they dethrone Wu (knowing I'm an early Imina this is going to complicated but anything is possible).
They are building the lore very well until now the danger ahead is to not make all of this building flop with a bad written ending/plot twist.
