For our weekly foray into the Distinguished Competition’s small-screen super-heroes: Supergirl is all about the girlfriends, and similarly The Flash primarily portrays the partying princesses.  Meanwhile Legends and Arrow have to run some errands and take gifts (a Deathstroke and a Mack) back to the store.  I may be a bit behind and have misinterpreted the synopsis, which appear after the cut.

 

(Synopsis cut and pasted from Trakt.com.)

Supergirl – Damages – When multiple children get sick from lead poisoning, Morgan Edge points the finger at Lena and blames her creation of the lead bomb she made to save National City from the Daxamites. While Lena knows she never intended any harm, she fears there may have been a flaw in her design, leaving her responsible. Kara teams up with Samantha to clear Lena’s name, but it turns out to be harder than they thought. Meanwhile, Alex and Maggie make a crucial decision about the future of their relationship.

The Flash – Girl’s Night Out – Having received an ominous threat from her old boss, Amunet, Caitlin fears that her past time as Killer Frost may be back to haunt her. Felicity comes to Central City to help the girls celebrate Iris’s bachelorette party, while Cisco, Joe and the guys take Barry out for a night on the town.

DC’s Legends of Tomorrow – Return of the Mack – When Nate thinks he has found a pattern to the anachronisms, it leads the Legends to London in 1897 to hunt down a time-traveling vampire. When they arrive in London, they run into Rip, but not everyone welcomes him back so quickly, leaving Sara to make a tough choice in the end. Amaya tries to connect with Zari, but she is still struggling with being part of the team. Meanwhile, Stein discovers what Ray and Jax are up to and is not entirely pleased.

Arrow – Deathstroke Returns – Slade returns and asks Oliver for help in tracking down his son. When they learn Joe has been taken hostage by mercenaries, their mission to save him gets complicated by a terrible revelation that could shatter Slade’s hopes of reunion forever. Meanwhile, Vigilante reappears in Star City.
