Really underrated fight for me. I love the dialogue between them. I haven’t seen much people talk about the fact that both Mori and Mujin Park were going to die at the end. The fact that Mori was fine with dying shows how much hate he’s pent-up.
Although we don’t know how “the captain” knows Jahad, we can assume that “the captain is a special person since he knew where Jinsung Ha was going to be locked up. Both “the boss” and “the captain” knew about Bam.
Tog theory:
“The boss” and “the captain” are the same person. They both apparently know Jahad (as in more than the average person on the tower). It’s obvious why “the boss” knows Jahad since he seems related to Jahad in some way due to their appearances.
