"The Darkness and the Light" is the fifth episode of the second season of The Flash, and the twenty-eighth episode overall. It aired on November 3, 2015. It acts as the first half of a two-part episode.[1]


Barry learns a new breacher, Dr. Light, has come through the portal and sets off to capture her. Jay tells Barry that Dr. Light was not a threat on Earth Two and that Barry can reason with her. However, during a fight with The Flash, she blinds him and drops some shocking news about Zoom. Meanwhile, Barry and Patty go out on a date.[2]


  • When Barry and Patty reflect on their near death experiences on their date, Patty says "We both cheated death". This expression is a recurrent theme in the Final Destination film series. Shantel VanSanten starred in the fourth installment.
