It’s back to business for Supergirl this week following last week’s epic four-way crossover with The Flash, Arrow and DC’s Legends of Tomorrow.
The spectacular event saw Kara (Melissa Benoist) targeted by her doppelgänger from Earth-X, a world run by Nazis. The doppelgänger, who was married to Earth X’s Oliver Queen (Stephen Amell), needed Kara’s heart to cure her illness.
Of course everyone pulled together and Kara’s life was saved. Meanwhile during the crossover Alex (Chyler Leigh) got drunk and hooked up with Sara (Caity Lotz), which made her reassess her decision to break up with Maggie (Floriana Lima) ultimately realising she made the right decision.
The mid-season finale is Reign. Supergirl investigates when a strange symbol pops up in National City. James is forced to step in as tension builds between Lena and Morgan.
