I'm not quite sure but I think the smartwatch are the digital keys Jamie was talking about. Cannot believe they…
Totally agree, unfortunately the writer failed in this aspect! I can give excuses to MJW tho, because we aren't supposed to know much about him in the early episodes, but the others..
what is jamie's power?She has shown nothing.. even her investigative skills are ordinary, worse than a normal…
I'm not quite sure but I think the smartwatch are the digital keys Jamie was talking about. Cannot believe they still didn't realize all victims wore the exact same. And for what you've said about Jamie, she is not worse than a normal human genius she is actually worse than just a smart one.. She keeps repeating the same thing over and over again, have no clues, no reasoning.. And above all that, I don't understand how and why she assumes things??
I actually like Gye Won as a character,just not sure of the actress playing her..Could they not have got a better…
Ok but you don’t have to use other actresses to bring her down, we don’t all agree. Because for me, I see that Chungah can’t act, Chaewon is a great actress but she has nothing to do with this drama.
My Speculation: Jungwoo knows the fire will happen no matter what, he cannot stop it because he is not the person who accuse it. He saved SMH to gain his trust and then “try” to kill him and take all the blame. In conclusion he’s protecting someone, and maybe more than one. This is actually very disappointing to me because I really want him to be the killer.
First, don’t forget that Jamie’s existence itself is questionable, and then Jungwoo’s being too friendly…
I was really hesitated to write this but now I’m glad I did! And omg you described him perfectly! Now I came to think about it, he is really as you said.
It feels you guys are judging Hyewon’s behavior without context, even someone describing her crush as possessiveness…
First, don’t forget that Jamie’s existence itself is questionable, and then Jungwoo’s being too friendly with her. We know as viewers he’s perhaps trying to trigger her memory by doing high fives and stuff. But from Hyewon’s pov, he’s just acting weird, and did she do anything? No, she just observes. So childish of her, she observes..
When Hyewon asked “Just the two of you?” first day meeting Jamie in the office, she stated that she is worried about Jamie, the new member who knew nothing about their boss. And then what happened? Jungwoo who is bad with directions lost the way and they couldn’t meet the victims’ families as they supposed to do. Later Jamie apologized to Hyewon for misunderstanding her question. They were clearly wanting to make a comic scene with him being bad with directions. But omg so childish of Hyewon, she wasn’t professional.
When she was mad about finding out Jungwoo was with Jamie the whole night, guess what? she was supposed to meet Jungwoo but he suddenly disappeared until the next day. Omg again, childish, she was jealous not worried. And in case you didn’t realize, Jungwoo intentionally riased his hand so she could know he got hurt. And also intentionally made her misunderstand what happened last night with Jamie. He did this again with the other members, I think he enjoys manipulating people.
Jungwoo and Jamie were alone in the observing room, other members said to Hyewon “They’re having a lovers’ quarrel,” and what did she do? distrupt them? No, she just waited and then said nothing, so childish. Imagine if she actually did something like entering the room so their conversation would end, or maybe asking them what they were talking about, then you guys gonna like it, you will get and an actual reason to criticize her.
And to be honest, I don’t get why and how Jamie’s suspecting Jungwoo? its just the writer being too dramatic. You cannot really blame Hyewon for being angry about it, there is nothing we could doubt atleast for now.
