"Never killed anyone before, but it's not murder if it's your double, right?"
Doctor Light to Linda Park
"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-2 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.
  • When speaking with Team Flash for the first time, Earth-2's Harrison Wells mistakes Eddie Thawne's name as "Ricky" while insisting that he's not the Reverse-Flash. This could potentially refer to the fact that Eddie's actor is Rick Cosnett.
