You might think you’re seeing double today when tuning into NBC’s “Days of our Lives,” but no need to get your eyes checked: Eileen Davidson is in fact appearing as two different characters. Today marks the day that the Emmy-winning actress appears as both Susan Banks (whacky mother of EJ [James Scott]) and Kristen DiMera in a storyline that brings the arch-nemeses face to face! But if that’s not enough to make you jump up and down in glee, get this: Davidson also appears on “The Young and the Restless” as Ashley Abbott today — which marks the first time in soap opera history that an actress is appearing on two different shows as three different characters in one day!
