In the Dark is the fourteenth episode of the second season of Designated Survivor and the thirty-fifth episode overall. It aired on March 21, 2018.
A power blackout in Washington scrambles both the White House staff and Hannah into tracking the source of an apparent hack into the grid. Damian breaks his tracking device to kill a Russian before the Russian can kill Hannah. Kirkman and Washington, D.C.'s mayor Ellenor Darby tackle local unrest during the power failure, and their success after an early misunderstanding makes Kirkman's mind up about his choice for vice president. Kirkman's brother delivers an unexpected but welcome surprise involving a bond payment deadline extension to Japan.
