'Sisyphus: The Myth' Episode 15: Will locking up Seo-hae help Tae-sul stop war as he can now see the future?
Tae-sul learns how Sigma plans on using his uploader to introduce the nuclear bomb into the city
'Sisyphus: The Myth' episode 15 will explain the main reason why Han Tae-sul (Cho Seung-woo) decided to lock Seo-hae in the bunker that he had built for her family's safety just in case they do not succeed in stopping the nuclear war that is set to take place in days.
This is the same war that Sigma had engineered from the start, even going to the extent of funding Tae-sul's company called 'Quantum and Time'. In this time travel show, a crucial plot driver is that preventing the future war depends on the protagonist's present actions to change the timeline enough to veer away from that outcome.
Of course, messing up the timeline has consequences but Tae-sul understands the repercussions now, probably better than Seo-hae, who has no understanding of the science or even the difference between teleportation or time travel.
Tae-sul had changed the timeline in a very minor way by asking someone for help. When that someone turns out to be Tae-sul's assistant who is in a coma in the present after being shot at, the risks are now clear.
This assistant is someone who was like a brother to Tae-sul and so when he returned, he also helped Seo-hae escape and find a route that will take her to the brokers who can transport her to the present from the future.
He also brought ashes of Tae-sul from the place where he was buried along with Seo-hae. Upon touching the ash, Tae-sul ends up seeing the future.
This future is a result of the nuclear bomb going off in the Korean peninsula. Now, having seen the future, Tae-sul seems to have a pretty fair idea of how he can thwart Sigma's plans. The first thing that he did was lock Seo-hae, the next thing that he planned was to confront Sigma and trick him into telling him about his plans, unintentionally.
Just as he had expected, he learns how Sigma plans on using his uploader to introduce the nuclear bomb into the city. Once he learns of this fact, he believes that he can see a future -- a future where he wins and not Sigma. That is at least what he tells Seo-hae over a call.
While Tae-sul is out and about trying to find a solution, Seo-hae gets help from her only friend in the present to break her out of the bunker. She even uses the weapons that is in the bunker to find a way out to help Tae-sul, and with just one episode left before the show comes to an end, we wonder how the two will stop the war. Or if they even will.
