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.
