Diane Cowell was the wife of Eric Cowell and the mother of Sarah Cowell. She was shot by agents who were attempting to capture her husband.
Diane and her daughter, Sarah, are tied up and guarded in their own house. Diane's husband sneaks inside and makes the agents fall asleep using his special ability. He unties Diane and Sarah, and they are about to leave, but when they open the door, more agents waiting outside open fire and kill Diane. Eric mourns Diane and cries over her body softly.
