thinking about how much taeju does for the organisation and how capable he is:
we see him actively training the recruits in the gym as well as being involved with running the cage fights and disciplining the members
he is already investigating the new drug when mj brings it up.
he is the one who knows when the boat came in and where it's docked. then he explains the manufacturing process to mj on the boat, also knowing where the lab itself is and telling him.
he's always between mujin and the threat, even almost setting himself on fire to make sure he gets to safety first.
he's the one tasked to find the rat who got the cops to the ship.
he brings up the issue of trusting jiwoo several times before it even becomes an actual issue.
jiwoo only mentions 3 cameras, taeju takes all of them down.
when the gym is attacked he sustains 1 little cut to his lip after before gangjae gets him at fucking machete point - like he literally fought off multiple men with knives and hammers with only his fists and only gives up his leverage when the men are threatened further.
he's wearing a chief mourner / host band at the funeral (two stripes) even though it's clear that actual family members are there. mujin isn't wearing a band at all.
mujin tells him to find gangjae. he says it's dangerous to move bc of the cops but does it anyway.
he is the one who knows when the other orgs arrive he is the one holding them back waiting for instructions.
he is the one sent to calm the buyers down while they work on rebuilding their product. he has enough sway with them to be downright threatening without losing their business, and they all look scared of him.
he goes to see who is blackmailing them. he doesn't stay to talk to the cops but it still could have cost him his life. proving that he was right to say it was dangerous to move. just not for the reasons he had in mind
