Dae-ho fans thinking they were gonna get an exploration of ptsd flashbacks only for Dae-ho to have a complete personality transplant and admit he lied about being in the marines
Hyun-ju fans thinking they were gonna get a bunch more badass scenes with her only for her to get killed off in episode 2 by the worst character ever
Jun-ho fans thinking he was actually going to be allowed to shine and impact the plot in a tangible way this time only for the writers to pull yet another "you could take him out of the show and the plot wouldn't really change"
Hwang brothers fans thinking they were going to get the reunion they were all waiting for only for Jun-ho to shout a few words at In-ho from a considerable distance away and then nothing more
Inhun / 457 fans anticipating the big reveal of who In-ho really is to Gi-hun only for it to last two minutes, with Gi-hun never finding out In-ho's true identity as Jun-ho's brother, no exploration into why In-ho became the front man, etc
Gi-hun fans thinking he would survive because surely after all he's been through he'll be allowed to live only for... yeah
