[Warning: The below contains MAJOR spoilers for the Season 5 finale of Supergirl, "Immortal Kombat."]

Kara (Melissa Benoist), Alex (Chyler Leigh), J'onn (David Harewood), Nia (Nicole Maines), Kelly (Azie Tesfai), and M'gann (Sharon Leal) got some help from Lena (Katie McGrath) in the fight against Leviathan in the Supergirl Season 5 finale.

Brainy (Jesse Rath), despite working with Lex (Jon Cryer), turned on the Luthor and put his own plan into motion to stop the immortals—by shrinking and bottling them. It worked but may have had fatal consequences for him. Is there any hope now that the others, alerted by Nia's dreams, know he needs their help?
