He couldn't have killed them. Could he? Everything checks out. His alibis check. Motives for the times he assaulted them couldn't point to him being the murderer. They're perfect coincidences but they check. Even the DNA? There's secondary transfer. Could it be his father's DNA someway somehow? His father is possibly alive somewhere? They lost connection at the point when he moved abroad.

Even if Shi-baek says he's the killer, I'm not believing him until the end of MIPTC.

No idea why they keep pushing these stupid fake-outs. If Shi-baek isn't the killer, it's super lazy. If he is the killer, it's supremely stupid. I was almost hoping that he would answer "No, I didn't kill all of them" because it wouldn't be a lie if he only killed one or two of the victims. Now, I'm pretty sure this will just be him "joking" again and going the dark humor route in the most annoying and unfunny way possible.

At this point, I almost hope Shi-baek did it because that, at least, would serve as a half-way decent payoff. I'm sick of the mysterious half-smiles and the perfect white knight routine (he was threatening the police chief over a mother and her baby, really?!) that's coming off a bit ragged by now.

Most importantly, it would finally give us the Shi-baek screentime that I've been sorely missing over these last four episodes and a probably riveting performance by Lee Kyu-hyung to boot. Plus, what's more poetic than the killer only being able to keep on killing because he happens to be useful to exactly the right amoral bastard? I'm just not invested enough in Shi-baek's shallow good guy persona, I'd rather watch him be perfectly unhinged and showing his teeth.

One thing I was surprised about: No mention of the police chief and his current health status. Is there a possibility he could serve as a potential witness later on?

Last but not least, some stuff that I liked:

- The hug. It's way too late for things to turn shippy but I adore a respectful platonic friendship between a man and a woman.

- Chak-hee going the medical malpractice route with her chip client. Now I really want to know what that thing is and if it has directly caused some of the woman's more disturbing symptoms.

- Finally some Shi-baek background info!

By now I am sure that Si-baek's brother is the real murderer. I remember Si-baek touching a roll of tape in his restaurant, which is surely the reason why his fingerprints were found at the crime scene.
My guess is that Si-baek will relativise his apparent confession at the beginning of episode 9 in that he committed the murders in his mind because the victims were guilty.

Nevertheless, Si-baek is definitely not an innocent, but at least has an "extraordinary" understanding of vigilante justice, considering how he chased the police chief down the street in his car.

Well now. I can't say I saw that confession coming. As it was a cliffhanger confession, I suspect we're being set up for a 'just joking ' scenario in the next episode. I'm also suspecting the brother. I figured brother in law as opposed to brother because I thought GiDo mentioned that he had 'her eyes' when referring to the chef's murdered wife. Having said that, I doubt if his hands are completely clean either. It'd be a turn up for the books if he is actually the killer.
I'm still enjoying the interaction between both leads, they spark off each other well.

I think killer is shi-baek's brother. They're not blood brothers, right?
I also think that neighborhood grandma is Shi-baek' mom
There are sooo many questions.
_who is the killer
_who killed shi-baek's brother's wife
_what was the above person's relationship with Mr. Jang.
_Who is the man who lost his memory and why it happened
_Who is Lee Dong-Pil
_What happened to Shi_baek's father
_What's the matter with Chak-hee's father

And the last question is why the writer just adds to the questions instead of answering the previous ones! I'm
very confused!!

I'm also operating on the assumption that Chi-sik (the restaurant owner) is the killer and that his wife's death is somehow related to why he's doing these killings.

However, I am utterly confused about Chi-sik and Shi-baek's relationship. Episode 7 tells us that they are "brothers" while the background check that Gi-do got for Shi-baek in Episode 8 said he had no siblings.

Speaking of which: why does Chi-sik hang himself only to slice off the rope at the last minute? Is that how his wife died?

Gido's remark that Shi-baek has Hee-soo's eyes also made me wonder if she could have been his mother. But if that's the case, does that mean Chi-sik is actually Shi-baek's father? I assume it's possible since she died 30 years ago; she'd certainly be old enough to be his mother.

I found it interesting that Byung-chun (the grandfather) assumed it would be Shi-baek's father who was the patriot who had been awarded the watch. Could it have been Shi-baek himself who 'earned' that watch? There were years of his life that are undocumented. And we still have no idea why he's so good at hand-to-hand combat.

At this point, I'm thoroughly confused about what I want — Would it be better if Shi-baek is the killer and we have a compelling reason for why? Or would it be better if Shi-baek knows who the killer is and is attempting to draw suspicion from them by doing the things that he's been doing?

Finally — I confess that I had a truly hearty laugh at the thought that Gi-do would have to pull strings to keep Shi-baek from being arrested because he's already publicly allied himself with Shi-baek via the campaign photos. It's so deliciously ironic that Gi-do is in the position of having to protect Shi-baek even while Shi-baek is (seemingly) plotting Gi-do's downfall.
