The CW Superhero Series Mid-Season Finale Trailers Tease More Weddings and Betrayal

     November 29, 2017


This week has already been an epic one for The CW. The network’s stellar superhero series SupergirlThe Flash, DC’s Legends of Tomorrow, and Arrow have already been enjoying solid seasons but all of the many, many heroes (and villains) came together for the epic crossover event, “Crisis on Earth-X.” But next week, it’s back to business as usual for each individual show as the superheroes prepare to air their midseason finales.

In celebration of that, we have collected each of the midseason finale trailers along with their episode synopses. Because of that, some spoilers follow, so if you’d rather go into the last week of 2017 CW Superhero Stuff cold, avoid reading any further. Still here? Good, because you’re about to see some interesting teases for the upcoming episodes. Kara will go up against an imposing Worldkiller, Barry squares off against The Thinker, the Legends will take on … vikings (?), and Oliver Queen finds himself with a betrayer in his midst. Expect lots of action, intrigue, and maybe even some cliffhangers as The CW draws 2017 to a close in preparation for a superheroic return in 2018.

Check out the trailers and synopses for each show below!

The Flash

“Don’t Run” — (8:00-9:00 p.m. ET) 

KATEE SACKHOFF RETURNS AS AMUNET — Amunet (guest star Katie Sackhoff) kidnaps Caitlin (Danielle Panabaker) and puts meta-dampener handcuffs on her to keep her from turning into Killer Frost. Amunet tells Caitlin she needs her to perform a tricky medical task and if Caitlin fails, Amunet will kill her. Meanwhile, The Thinker (guest star Neil Sandilands) traps The Flash (Grant Gustin) in a speedster-proof prison. With the clock ticking, The Team doesn’t have the time or resources to track both Caitlin and Barry so Iris (Candice Patton) is forced to choose who to save. Stefan Pleszczynski directed the episode written by Sam Chalsen & Judalina Neira
