Just done watching episode 2. Some bit more insight into Jingyeom's personality. As he himself says, he doesn't treat everyone as a human. It's a likely indication that as with the bunnies and snipping off their ears when he was a child, if he has no relationship with a person/being, then there are none of those emotions (logical or otherwise) attached to them. That's why he could so readily shoot that fella twice without batting an eyelid. Fair to say that even if his prefrontal cortex is underdeveloped, it doesn't mean it doesn't work. Just likely takes more effort, and his responses for most parts are learned (such as not to kill) than a reaction to an emotional stimulus. He strikes me as a cross between Data and a Vulcan (of Star Trek pop culture).
What the time card does is a curious thing - I'm thinking it opens a portal of some sort? The one he activated was his mother's? Making the things around his home float about seemed like there was some attempt by the device to bend space and time.
I too am liking this confrontation with his father and them being set up as adversaries, even if for a short while. I am expecting dad to become a partner instead once he finds out mum was murdered. And speaking of mum, I expect that Prof Physicist is mum. Just which time line is she from?
Separately - do Uni profs in Korea really yell at their students like they're in middle school??
