Fridge / The Good, The Bad, The Weird

Fridge Brilliance

• Do-won is almost immediately thrown out of the train by Chang-yi's hammer/club-wielding thug, whilst Tae-goo is able to, if not overpower him, at least fight on equal enough terms until he gets his gun. This makes more sense when you discover that Tae-goo is the Finger Chopper.
• One of Chang-yi's gang members calls Tae-goo a loser. Chang-yi immediately orders him to duel and kills him. This seems like a bit of an overreaction from even Chang-yi, until you remember who took his finger - how dare the mook say that the man who beat him is a loser.
• Tae-goo is quite cavalier about breaking into the general's train car without knowing anything about his guard detail, yet he quickly guns down all the guards and calmly reloads. This foreshadows the revelation that he's a much more dangerous man than he first appears.
