Later on, Julia’s parents stop by Melinda’s house and inform Delia and Eli that in their daughter’s diary, she confessed to killing her friend. At first they are unsure if she is a good or bad ghost, but later on realize that she wasn’t trying to kill her friend, but help save her from her sickness.
Aiden and Julia are off to an old train station. Julia has been so sick in the hospital that she did not know about the station being abandoned. They wait there because the Shinnings are supposed to come and protect her from the Shadows.
Jim finds out from a bus driver that Aiden got off at an intersection that is near a forest. He sees Aiden’s toy car and realizes he is on their tail. The further he goes in the forest, the more of Aiden’s toys are leading him in the right direction. After talking with Melinda they both understand that this is a path to their son.
Aiden and Julia are about to leave when she sees the Shadows approaching. Aiden tells her to stay in the light and they are about to be defeated by the Shadows, but Aiden saves the day by placing all the shiny objects around her.
