Synopsis:
A missing woman with a rare disease resurfaces in suburban Massachusetts, causing pain and subsequent death to those she comes in contact with in a diner before her own head explodes. When the scene is investigated, dangerous levels of radiation are detected, and unusual circumstances surrounding the case point to illegal human drug trials. Meanwhile, Walter craves cotton candy and Peter strikes a bargain with Nina Sharp to get information on her competition who is repsonsible for the drug trials. Olivia reveals that she shot her stepfather at a young age to save her mom from his abuse. He survived and continues to haunt her by sending a birthday card to her every year.
