In last week's episode of "The Flash," Joe (Jesse L. Martin) and Cisco (Carlos Valdes) uncovered the disturbing truth: Harrison Wells died fifteen years before they met him. Now, Barry (Grant Gustin) and his friends must confront the Reverse Flash (Tom Cavanagh), their most dangerous foe to date.
The new trailer shows the consequences of that discovery, as Team Flash finds themselves face-to-face with the man who killed Barry's mother. Outsmarted and outpaced, Barry will need help in order to finally bring the case of his mother's murder to a close.
"The Flash" airs Tuesdays at 8 pm EST on The CW.
