Luz is adopted by the wests. 4 years later, while working as an assistant in the forensics lab, she is struck by lightning the same time that the particle accelerator, and goes into a coma. After waking up, she learns that she has superspeed and becomes the flash. Now, 19, she finds Owlbert and goes through the door, back in the Boiling Isles. What will happen?
