Sun talks to Ji Yeon, threatens to shoot Ben

Sun is sitting in her car where we last saw her in episode 4 "The Little Prince." She receives a call from her mother Mrs. Paik (we've never learned her first name) who asks when she is coming home and tells her that Ji Yeon wants to talk to her. Sun tells Ji Yeon that she will be home soon and that she's found a new friend for her in America, Aaron.

Sun then proceeds to get out of the car with the gun she received under the chocolates and proceeds towards Ben. She holds the gun on him as Ben says "I didn't kill your husband Sun... and neither did anyone else because he's not dead." He then tells her that he can prove Jin is alive. Sun's eyes begin to tear up.
