Mrs. Woo

Ms. Woo is a minor character in Train to Busan.

She is protrayed by Lee Joo-Sil.

History
She is Seok-woo's mother and Su-an's grandmother. Like her son, she is divorced. Seeing her son's obsession with his work, she really wants him to be able to pay more attention to Su-an and try to reconcile with his wife. Seok-woo tells him he'll manage, and this is the last time his mother is seen.

However, when the epidemic broke out, in the train to Busan, Seok-woo called his mother, who was infected. She asks him to take care of himself and Su-an before saying "I love Su-an, but she only wants to see her mother," becoming madly upset about this, and finally, turning into a zombie.
