At the DEO they're having a hard time making sense of what their subsequent stage is, the point at which they realize that Maggie is gone.

At the jail, Maggie breaks Thompson out utilizing taken DEO tech, just about to get him out... until they run into Supergirl, who convinces Maggie to stand down. Supergirl addresses Thompson about how she realizes his child is anything but a terrible individual on a basic level, and she figures he can step up as a dad and help Malverne make the best decision. Thompson discloses to Supergirl that there's one spot he can consider where his son may have taken Alex. Kara and Maggie show up at the warehouse just as Alex's air runs out. As she begins to drown, Kara punches through the cell's glass and Alex spills out alongside the water. Kara and Maggie embrace Alex, who is shaken and injured, but alive.
