Oh I find the double lie interesting not the flinch, he's been living in chaos and it seems like it's every person for themself out in the real world. So even pulling the knife as an unconscious defense mechanism seems expected. But we saw the flashback so why lie to himself that it was cuz of guwon. I just wanted to make note of that
When he flinched in the flashback the hand and arm had no tattoos so he lied to guwon and himself
