With the Crisis on Earth-X crossover event taking place starting Monday, the CW has decided now is the time to catch up on episodes of Supergirl, Flash, Legends of Tomorrow, and Arrow. You can watch all of them on the CW App on your mobile device or on CWTV.com. And they make a valid point, as both the app and the website only carry a certain number of episodes with the first two of each season already having been removed and the third episode about to go in three days.
To go with the push, they've released trailers for each series that includes footage from the already aired episodes and from the upcoming crossover event. Here we have the catch-up trailer for the third season of Supergirl. This season started with Kara (Melissa Benoist) reeling from the loss of Mon-El (Chris Wood) and trying to focus on being Supergirl and putting Kara Danvers aside. We've met Morgan Edge (Adrian Pasdar) and Samantha Arias aka Reign (Odette Annable). We met some classic comic characters like Bloodsport (David St. Louis), Psi (Yael Grobglas), and Saturn Girl (Amy Jackson), and were introduced to M'yrnn J'onzz (Carl Lumbly), the Martian Manhunter's father. And we'll be getting more members of the Legion of Super-Heroes in the future.
Supergirl airs Mondays at 8 p.m. ET on the CW.
