Each week on Ghost Whisperer, we learn more about the extent of Aiden's powers, which is becoming more of a concern for Melinda since she can't see everything Aiden sees and doesn't know how to protect him. Tonight, however, Melinda and Jim face their worst nightmare when their son Aiden disappears.
When we last saw Ghost Whisperer, we learned that Aiden's new ghost friend was hiding in the closet. "Lost in the Shadows," the ninth episode of the fifth season, gives us a glimpse to this dead little girl's back-story where we learn that she passed away from leukemia and why she's attaching herself to Aiden.
Melinda worries for her son's safety when the ghost threatens Melinda to stay out of her way but it only gets worse as the little girl, who seemingly doesn't care whether Aiden lives or dies, lures Aiden on a dangerous path. The question is: Is she really leading him to harm's way or is she protecting him from something else?
Ghost Whisperer airs tonight at 8pm on CBS.
