As we first reported, Lucy — sister of Lois Lane — is brash, funny and successful in her own right. In keeping with DC Comics lore, she will also be an ex-girlfriend of Jimmy Olsen (Mehcad Brooks), Kara’s new CatCo media conglom colleague. (Considering Kara’s immediate crush on Jimmy in the series’ pilot episode, Lucy’s presence will not be a welcome one.)
Lucy Lane is one of several DC Comics characters to have adopted the Superwoman mantle, though there’s no word yet on whether that will play into Dewan-Tatum’s role on the show.
Dewan-Tatum is the latest in a string of Supergirl castings, including Chris Browning (Sons of Anarchy) as villain Reactron and Peter Facinelli (Nurse Jackie) as iconic DC Comics character Maxwell Lord.
Supergirl debuts Monday, Oct. 26, at 8:30/7:30c, before moving into its regular Mondays-at-8 time slot.
