Supergirl Season Finale Description: “Battles Lost and Won”

The CW has released an official description for the June 18 season finale of Supergirl.

Supergirl Season 3 ends with an episode titled “Battles Lost and Won” – a title first revealed here at KryptonSite months ago. The official description can be found below; be warned, it’s really, really short.

SHOCKING SEASON FINALE – Supergirl (Melissa Benoist) and team take on Serena in an epic battle for Earth. Jesse Warn directed the episode written by Robert Rovner & Jessica Queller (#323). Original airdate 6/18/2018.

And that is all they wrote, leaving us to speculate what more we might see, at least until a trailer or some photos head our way. The season finale airs June 18 on The CW.
