SIGH, what can I say about this episode without being annoyed at the stupidity and arrogance. How did he know how to use the dohickey? When that other man become his father? Where was the alternative version of him go in that new future? So many bad decisions. So little explanations.

yay it picked up the pace! Yes it is kind of strange in the other universe, there is no other version of him. I know it is going to be like this, too. Now, he is the one who killed his father. Eeeps!

I didn't like the 'greatest good of the greatest number' dilemma that Saeha was trapped in or rather that he trapped himself in. Even if he had to do the time-travel himself, he should have focused on potentially achievable goals such as traveling back in time just enough to save his mom from the lethal injection (assuming that's even possible with the time-travel paradox the show is presenting). Doing things that would directly impact the history of mankind for the last 20 years should not have been the first choice. Still I'll give props to Seo Kang-joon for making his frustration and his pain believable.

Well it picked up the pace but..... I don't love the execution, nothing has any real purpose, we still know nothing about the ghost, it makes zero sense that he can even try to set up the grid without her given he couldn't even finish what she started, the whole thing just feels like it wasn't sufficiently planned out by the writers. This series has a cool premise and some interesting characters, but it feels like it's more holes than plot at this point.

I have been a fan of Seo kang -joon since Watcher and I thought that he was amazing in ep 7

I dropped that in this week😁Last 3 episodes were so weak!!

I loved this episode. As a fan of sci-fi I always love a good time travel story, and so far this one is good.

Just one thing: although we all believed Saeha is the boy the janitor is hiding, I realised he isn’t. In fact, he is the boy looking through the window on episode 1 and talking to his mum on the phone. Saeha is not traumatised by the janitor’s death but by his dad’s death. This makes me wonder if the janitor’s son is SaeBuyk. It would make sense.

By now Saeha understands that no matter how hard he tries, he can’t change the fact that saving his parents would mean the grid would not be set up and humanity would suffer. He initially doesn’t care because he wants to enjoy his family time, but once the fairy tale is over, and he realises what his selfish decision implies he decides to travel back, to try again, and when he does, reality hits again: one way or another his father must die. And I think the fact that he saw SaeByuk is related to it.

So now that he actually understands what happened, he must go back to the point where he doesn’t want to to: to that lab to free the Ghost.

Still wondering how the Ghost traveled in the first place and I like your theory that she lived in the no Grid alternative reality and she tries to prevent human kind to suffer (the fact that she is always covered may be a hint), and why is it important to keep SaeByuk alive. Knowing writer-nim I know we will get answers.

The pace of the drama picked up in these two episodes. I like the idea that time doesn't flow, and I'm wondering if somehow that was why there wasn't an alternative Sae-ha because in this scenario parallel universes don't exist. But I can't even begin to imagine what the alternative is.

It bothered me that when they caught the woman all they could do was restraint and physically torture her, when they actually needed to know what she knew and to benefit from her superior technology. They were so predictably stupid and brutal. Mankind is depressingly predictable.

Threatening with guns was a terrible set-up or terrible editing. In many frames, the two doctors were behind Sae Byuk when she was pointing the gun either at the director or at Sae Ha and those two could have easily over powered her, while Sae Ha was distracted.

If Sae Ha is an exact replica of his dad, how come neither the Director Sun Wool nor the security show any sort of recognition and just let him work for the grid? For an organization that conforms to confidentiality as highest priority, they seem lacking to allow a family member of an ex- employee who died on the field, to work in a team whose sole job is to trace the ghost. Wouldn't they have perceived his motives or do a background check when he was hired?

I have loved the suspense and intrigue up until this episode.

have always disliked time travel shows because it never makes sense to me - when a person can be back in time and meet themselves, and the butterfly effect, etc. just doesn’t fit logically to me. So was shocked by the avalanche of these in this episode. Absolutely hate it. Sigh.

Grid continued to make the most sobering exploration on humanity and sense of normalcy, on the inevitable trade-off between advancing knowledge/technology and morality. I know how the writer seemed to knowingly relegated the sci-fi elements as mere plot device to present to us those dilemmatic situations. But I couldn't begrudge that decision if the intense exploration in this eps was the result.

It was exhilarating to see the usually composed Sae-ha spiraled into the pit of desperation that then fueled this week's plot development. After seeing Sae-ha being driven by one ultimate goal for long stretches of eps, it was oddly relieving to watch him being a bit selfish by settling into the alternate 2021. The timeline where he got to live comfortably with his birth parents, forming a tight-knit and loving family where, for once, his life is perfect. Except for the fact that the world outside his safe, luxurious sanctuary was barely recognizable.

It was fascinating to saw Sae-ha struggled to feel entitled to his alternate-timeline good luck, because he is an intrinsically good person and his conscience couldn't just accept that change at the cost of so many people's lives. The drama might not give us the ghost's justification for the death of the janitor, but it's a very interesting conundrum to see Sae-ha (and consequently, us) put into her shoes. Suddenly the question of one life vs. 2/3 of humanity became even more complicated. Should he pretend not to know when he is the only one who can make significant changes? Would it push him into god-complex if he decided to sacrifice that one life (and his own rosy future) for the sake of humanity? What will set him apart from those higher-ups who preached about the greater good then?

More than just watching Sae-ha confronting his own idea of fairness and justice though, I was even more impressed by what the alternate timeline presented to us. How people and their greed and feel of superiority was at the base of many seemingly advanced tech-induced problems. Because it's not Grid and the ghost that made a compromise on citizen's privacy and knowledge of their own world in the original timeline. And it's not the solar wind disaster that pushed the gap between the rich and the unfortunate even wider in the alternate 2021. It's the age old dilemma of ethics vs. scientific progress vs. power all over again, and it's never easy to answer in whatever alternate universes this drama could conjure up.

It also tickled me to see the slight poke at the apparently very flexible definition on "normalcy". How despite the constant grumbling, the frustrating secrecy and limited privacy was seen as inevitable reality by people in the original 2021. Meanwhile physical disfiguration and disability was seen as equally inevitable and common in the alternate 2021. It's amazing what people are capable of adapting to. Or maybe those situations actually talked about the sense of complacency that...

I'm not sure if anyone noticed but Kwon Soo-geun is supposed to be Sae-ha's father and Soo-geun was on the phone with his son who was at home. He was on the phone with little Sae-ha while the janitor's son was in the building. Sae-ha can't be the janitor's adopted son. They made us think Sae-ha was the janitor's son but we didn't realize that the Ghost had killed someone else that day which was Sae-ha's father. Even the child actors who played young Sae-ha and the janitor's son are two different people. Sae-ha's father wasn't even dead yet so why would Sae-ha have been adopted by the janitor already? That doesn't make sense. The janitor's son and Sae-ha must be two different people.
