Jong-gil

Jong-gil is a minor character in Train to Busan.

She is portrayed by Park Myung-sin.

History
She is first seen inside the train along with her sister In-gil as In-gil tries to give her a boiled egg, which Jong-gil refuses saying that they'll get off at the next stop. She is later seen again, watching the news and complaining about a riot that was currently happening somewhere.

She along with her sister are seen waiting for the train to stop for Daejeon, and once the train arrives she along with everyone else are attacked by dozens of zombified soldiers that were stationed there to quarantine them. She and her sister are able to make it back to the train but she is separated from her sister when a zombified soldier falls between them. Jong-gil is saved from a zombie by Ki-chul and Jin-hee, and is able to get in the main car with the remaining survivors and is left worried for her sister. She is later seen one more time when she notices survivors coming to the main car and also that her sister was among them. As a result, she desperately attempts to stop the other survivors from blocking the door but is pushed back, witnessing her sister being attacked and zombified, leaving her shocked and saddened. Later when Seok-woo and the others are forced to go into another car, she gets angry because of the selfishness of the survivors, so she walks towards the door and sees her sister among the zombies. They both put their hands against the door trying to touch each other, saying goodbye. She then thanks her sister for everything and allows the zombies to enter and kill the remaining passengers and allow her to be with her zombified sister.
