After hearing about David Rosen's (Josh Malina) two-timing ways, Susan Ross (Artemis Pebdani) is finding it hard to concentrate on debate prep. When the President (Tony Goldwyn) finds the V.P. staying late at work one night, Susan seizes the opportunity to ask him why he cheated on Mellie (Bellamy Young). Fitz explains although he can't directly answer the question of what would bring a person to cheat, if she feels like someone is cheating they probably are. With this, Susan sadly knows how she needs to move forward with David and is able to refocus on politics. From Season 5, Episode 15, "Pencils Down" of Scandal, which airs THURSDAYS 9|8c on ABC.
