Rebecca first came to scene looking for answers about the death of Brigid O'Reilly, a close friend to her, as well as a fellow police-detective. At the time, Rebecca did not know that Brigid had not died, but had become the entity known as Mayhem
. After a chase and accusing "Mayhem" of having something to do with Brigid's death, Mayhem finally told Rebecca the truth. She is one of the few people who know that Brigid and Mayhem are in fact the same person. Rebecca hasn't been seen since Cloak and Dagger's second ongoing series ended. Her whereabouts are therefore unknown.
