It appears that Supergirl has flown to a galaxy far, far away to acquire her very own lightsaber.  Lexi Alexander, director of the latest Supergirl episode titled Truth, Justice, and the American Way, took to Twitter recently to share a behind-the-scenes photo of herself, series star Melissa Benoist, and co-star Chyler Leigh (Alex Danvers) brandishing their own fierce lightsabers.  See Alexander’s post below:  We may have had some fun on that set @MelissaBenoist @chy_leigh #Supergirl pic.t
