A third promo for this year's Arrowverse crossover event, Elseworlds, is now online, and this time it's Supergirl's turn to fall victim to whatever alternate reality-based experiments John Deegan (Doctor Destiny?) is conducting in Arkham.
Though Kara (Melissa Benoist) appears to be herself, her adopted older sister Alex (Chyler Leigh) most definitely is not, as she locks the Girl of Steel away in what appears to be a version of S.T.A.R. Labs after referring to her as "despicable as they come, dangerous, and clearly crazy."
The Arrowverse crossover begins Sunday, Dec. 9 with The Flash at 8 p.m., then continues on Monday, Dec. 10 at 8 p.m. with Arrow, and concludes with Supergirl on Tuesday the 11th at 8 p.m.
