I think we found out in episode four that her father wasn't her real father. However they didn't come right out and say that, they just hinted at it. If she really was the girl from back then and was a Beta test for HumanB then he's definitely not her father. I just called him her father to make things more clear in the message above^^.

I think the fake Crown Prince is scared because they poisoned him to where if he doesn't eat that flower every mid-month then he'll die. So basically if he betrays them he dies. Again I agree with you about him not telling the Queen, he could tell her and the Bad people wouldn't know. Lee Seon (The fake Crown Prince) doesn't want to do anything but he's forced to because they won't give him the flower each month to survive if he betrays them. Hope that makes a few more things clear! :)

I think Bluebird leading him to that location was her helping him remember his forgotten memories. She has the power to unblock them so idk maybe it's possible?

Sometimes the shorter it is the better. Instead of dragging it out or putting in too much filler makes it better!

I think she's good, she was part of the Beta testing for HumanB that's why she had no emotions? And now she can't remember anything just like Joonhyuk (Bumgyun) can't really remember any of her past too. Is she an Alien? Possibly? And maybe her father (The Professor) is using her?

As far as episode 16 no, she does think he looks an awful lot like the late King did when he was young though. I think she definitely suspects that Lee Seon is not the actual Crown Prince. But as of now it hasn't been said whether she actually knows or not.

I think it'll get better. We're almost halfway through the drama and stuff is starting to happen again. Sohyun's character is supposed to help the King grow as a person and she has. Whether it's from the death of her father or feeling like he betrayed her, he learned he can't just make foolish moves. I think she'll play a more important role later, if she doesn't I'll be let down because like you said she's such a good actress. As for L, I think his real development is coming. Like once he finds out the Queen's trying to dethrone him and that Sohyun's character is in love with the still alive Crown Prince I can't see him sitting still. I have a feeling he'll be a bit peeved they like each other. But again this could be completely wrong and I swear if they waste the talent they have with them I'll be disappointed!!!!

That's true but she was adopted from a fairly young age so it's common to have a name change. Yeah it's a spoiler since it leads to us finding out she's adopted but really her last name gave it away. At the moment I'm really more interested in who Park Kwangho (the dead one) is. How did he find out about a case from 30 years ago when the files are all burnt unless he was a family member of a victim or could it be possible (future) Park Kwangho time traveled as well?

That's what I was thinking too at the beginning because they said he had stopped killing. What kind of serial killer just stops killing unless you know he's dead or arrested? He could've time traveled back with Kwangho or something? But apparently he's committed a lot more murders than we know of yet!

I think it's around the same, one of the cases in both of them are similar to one another. I love them both. I think they both have the same aspect. In Signal the past can change because of the walkie-talkie, in Tunnel the guy from the past goes into the future. If he returns the past could change, right? This isn't a spoiler because nothings happened yet but my guess is once he returns everything will change?

The future Park Kwangho's birth date didn't add up to when Yeonsook was pregnant so I knew he wasn't Kwangho's son. I mean unless she had twins but I doubt that. I think the future one has something to do with it. How else would he know of a serial murder case from 30 years ago unless he wasn't directly involved somehow? Maybe he had a family member killed by the serial killer or was a witness to one?

It's not really a spoiler because you find out Jaeyi is Yeonho the same episode Kwangho finds out he has a daughter and finds out her name. If they hadn't shown the whistle then yeah it would've been a spoiler. But they've been hinting at it for a while. Between the dumplings and Jaeyi's last name being Shin (Which is Yeonsook's last name) it's already obvious enough.

It's just the poster, if anything him facing away from us builds suspense. Which is one of the genres the movie's in.

A lot of American shows are all about sex. Maybe you're watching teen shows or kid shows? Have you seen American Horror Story, Shameless (literally has a sex scene once every episode I swear),Grey's Anatomy had a decent amount (I don't want to say it completely revolved around it but it was definitely present), and there are plenty other shows that have useless sex scenes in American TV. I, myself don't personally watch these shows (I have seen all of American Horror Story though), a family member watches these and the amount of it just makes me sick. Like I get it every once and a while is alright, or if it furthers the plot in some way that's fine too but do we really have to see two people get it on every episode? Violence is alright (I agree some is extreme) and I'd say it's around the same as Korea's. If Korea actually uncensored stuff it'd be even closer to being the same.

I read a post where the writer was thinking of making a season two so maybe stuff will be cleared up then.

There may not be one since the ban of Korean entertainment in China.

China put a ban on Korean Entertainment. So k-pop groups can't perform there and no drama with Korean actors/actresses in them will probably air. Hopefully the two countries amend things and it actually airs in 2018!

I totally agree with you on that. They should've not drawn it out as long as they did. This genre is a little hard for some people to get into. I wasn't sure about it myself at the beginning but I stayed because the acting was pretty freaking decent. And I'm glad I stayed, it made me think haha.

Sorry I meant were*, the mistake occurred because it was 4 am where I live. So basically what I was saying was we were meant to find out early on. Basically the whole purpose of this drama is for us to question "Are psychopaths born or are they made from the situations people endure as children?" I agree that they revealed who everyone was too early (especially for my liking) but I also got why they did so early.
But yes I totally get what you mean! Sorry about my mistake lol.

I think you were meant to find out early on who the Killer was and who Min was. That way you the viewer gets an eerie feeling whenever they are on screen. I just finished watching it and to me the whole purpose of making it easy to know who was who was so we would question everything. I know the whole I was wondering why Min knew the Killer. However the ending was just...I needed closure. For me it seemed like they were setting it up for another Season but they should've just ended it.
