Fan Casting Dr. Valerie Perez in Greg Berlanti's The Flash

Dr. Valerie Perez is a brilliant physicist with rock-star swagger and a sharp, flirtatious edge. Initially Barry's adversary, she becomes his ally, his teammate, and his lover—the woman who teaches him to feel. She uncovers Thawne's conspiracy and pays for it with her life, brutally murdered by the man she once trusted. Her death breaks Barry's heart and becomes the catalyst for his final confrontation with the Reverse-Flash.
