However, Rachel released Hellfire and made her way out of the cathedral. 

This was mere moments after it emerged that Rachel was part of a prophecy and the destroyer of worlds. 

With Dick and Kory trying to find out everything they could, they realized they would need to keep Rachel away from everyone. 

Dick learned that the Nuclear family had murdered Amy, and he was annoyed. 

Dawn was in a critical condition and Hank left it up to Dick to avenge what happened to her. 

The Nuclear family was given one final chance with a new father to take down Rachel.
