I Hate a Mystery! The Adventures of Supergirl 4 Review!

Previously, when Kara encountered Psi in a dream-state, the disembodied figure planted a seed sending The Girl of Steel to the Fort Rozz crash site in the desert. Kara believes that she and sister Alex are there to collect Psi's physical form - her body - from the crash site and re-bury it so she can finally be at peace. In reality, the sisters encounter Kryptonian robots. They discover that Facet, one of Fort Rozz's guards has been watching Kara from afar.

Now, Facet is ready to complete Supergirl's training so she can become one of Krypton's Finest.

Meanwhile, Vril Dox monitors the DEO agents that are supposed to be monitoring him.

Sterling Gates deepens the mystery. Gates reveals that Kara is not so much a fan of mysteries as Clark is. Carmen Carnera and Sandra Molina handle the imagery.

Red Tornado is once again mentioned.

Facet tells Kara to ask her mother for more answers. That's where the trail leads...

The Adventures of Supergirl 4, "Sistery Mystery (Reprise)" and "our Backs to the Wall" earns three stars.
