Labs’ Caitlin Snow (Danielle Panabaker), Rosso rekindles their friendship after they are reunited by an unexpected event. But their longtime bond is quickly shattered when the doctor’s desire to defy the laws of nature takes him down a dark path…one that transforms Rosso from an old friend into the most chilling villain Team Flash has ever faced: the monstrous Bloodwork
