Armek, a White Martian, descends on National City intent on taking M'gann back to Mars to face her punishment as a traitor. Hank and Supergirl determine the best way to keep M'gann safe is to bring her to the DEO. However, when it is revealed that Armek shape-shifted into M'gann and is now loose in the building, the team realize he could be disguised as any one of them.

The gun that Alex uses to shoot the alien and save J'ohnn was drawn by Chyler's 13 year old son, Noah, who drew it, showed his mum, Chyler, and said "I think Alex should have a gun like this."
