The Flash: Season 5
She attacks the CCPD vehicle that was transporting Gridlock to a secure compound because she needed his help to pull off a heist on an airplane. First facing off against Team Flash, she later used her former identity as a flight attendant to get inside one of the flights. As revealed there is a Metahuman kept inside that she wants and they get there, knocking out the guards and taking possession of it but Team Flash breaches in thanks to Vibe. She, Block and Gridlock face off but are knocked out and their mission fails, or so it seems. When the plane crashlands, she and Block get out, disappearing into the night, leaving Gridlock behind.
