Supergirl (Melissa Benoist), Alex (Chyler Leigh) and Lena (Katie McGrath) were transported into Sam’s (Odette Annable) mind of the latest episode of Supergirl.
They found Sam and Julia (Krys Marshall) fighting to remember their human lives and they used Sam’s daughter to get Sam to awaken her body on Earth, switching places with Reign. Sam activated a location beacon for the DEO to find the Fortress of Sanctuary and Supergirl, Alex and Lena were pulled out of Sam’s mind by Brainy (Jesse Rath).
A fight at the Fortress led to Purity and Pestilence (Angela Zhou) to kill each other. Reign absorbed their powers, the Fortress collapsed and she went decided to go after Sam’s daughter.
Meanwhile James (Mehcad Brooks) was tasked with finding out if Lena had any more kryptonite and he lied to Kara in a bid to prove to himself that he could trust Lena.
Elsewhere James told Lena that he was Guardian and she told him that she made the kryptonite that she’d used on Reign.
The next episode of the season is Shelter from the Storm. Supergirl and Alex fight to protect Ruby from Reign. Supergirl and J’onn receive some shocking news when they seek help from Sam’s mum.
