A Midseason Finale With A Bang
♦ Supergirl has survived this week’s CW crossover with DC’s Legends of Tomorrow and The Flash and Samantha Arias (Odette Annable) completes her tranformation into the World Killer Reign in The CW’s trailer for the Supergirl midseason finale, ‘Reign’…
Here’s the episode synopsis:
Supergirl (Melissa Benoist) investigates a mysterious symbol popping up all over National City, tracing its origins back to an ancient prophecy and the mark of the World Killer, Reign (Odetee Annable). Meanwhile, the tension between Lena (Katie McGrath) and Morgan Edge (guest star Adrian Pasdar) continues to build, causing James to step in and offer up some protection, and possibly igniting a spark in the process.
After this, the show takes a break until after Christmas.
