Those Aren’t The Alps
Supergirl and Lena head to Stryker’s Island after receiving a tip that Lex didn’t just escape this once, but has been coming and going from prison as he pleases. Lena uses that information to convince the warden to let the two inspect Lex’s cell for any clues that might point them to where he is hiding and what he is doing. Lena recognizes the family chessboard and finds a note from Lex in one of the pieces, just like they used to do when they were younger. Further investigation reveals Lex’s journals hidden inside the board itself.
Otis arrives and releases the rest of the inmates, telling them over the prison’s intercom that the one who brings him Supergirl will be released. Supergirl locks Lena safely in Lex’s cell to go through the journals while Supergirl deasl with Otis. Lena gives Supergirl a shield against kryptonite, in case Otis is still sporting his Metallo build.
Supergirl makes her way through the prison and fights with Otis. During the conflict, her kryptonite shield is shattered, forcing Supergirl to flee. Dressed as Kara, she is able to give Otis the slip. Kara is ambushed by Steve, the inmate whose cell was next to Lex’s. Steve recognizes Kara because he runs the prison’s newspaper. He tells Kara that he can get her information on Lex that he wouldn’t give Supergirl. Before he can, the National Guard arrives and comes in after Kara.
Back in Lex’s cell, Lena uses the memories called up from Lex’s journals to find a secret door on the wall of Lex’s cell. Supergirl follows Lena inside, where they find Lex’s secret prison headquarters. While the two watch on the monitor, Lex directs Otis into his cell, where Lex overloads Otis’s suit, causing him to explode in burst of kryptonite as Supergirl flies Lena away.
Supergirl believes that Stan has a point. If she is the government’s target, then innocent people in her vicinity are likely to get hurt. It’s time for Supergirl to lay low for a while and let Kara use the information Steve stole from Lex’s computer to find a clue to stopping all of this.

When Lockwood returns, Haley complies with the Lockwood’s request, but instead of summoning Supergirl, Haley sends signal that it’s a trap. In response, Supergirl goes dark by turning off her monitoring equipment. Enraged, Lockwood confiscates the weapons and convinces the president to deputize the Children of Liberty.
