Tonight Supergirl returns to The CW. In the last episode, Supergirl and the DEO captured a second Worldkiller, Purity. As Alex and Kara interrogated her, hoping to get some info on how to defeat Reign, Purity used her sonic scream to escape from her cell and get away. Meanwhile, J’onn, Winn and Mon-El teamed up to fix the Legion ship. During one of their conversations, Mon-El revealed that he only married Imra in order to unite Titan and Earth, not out of love.

Later, Purity and Reign teamed up to attack the subway, but our heroes managed to fend them off. As the Worldkillers were leaving, they promised that Pestilence would soon join their team, and that then they would be unstoppable. After things settled down, Mon-El told Imra the truth about their marriage, and that he may still have feelings for Kara. Imra responded with the news that she, too, was hiding something—the true purpose of their mission (though we never get to hear what this is). As the episode ended, Sam’s eyes once again flashed red, this time in front of Lena, who announced afterwards that she knew what was wrong with Sam.

Will the group be able to stop Worldkillers before it’s too late? What does Lena think she knows about Sam and the reasons for her blackouts? What is Mon-El and Imra’s true mission on Earth? Will Mon-El confess to Kara that he still has feelings for her? And what other dangers await our heroes in this final stretch of the season?

In tonight’s episode, “Schott Through the Heart”, when Winn’s father dies, his estranged mother tries to reconnect and explain why she abandoned him; a copycat Toyman attacks and the two must work together to stop him; Mon-El tells Kara something important about the Worldkillers.

Tonight I’ll also be watching/recording The Crossing, Good Girls, The Resident, iZombie, The Terror, UnREAL, and Final Space.
