This week on “Supergirl,” Cat Grant (Calista Flockhart) made her exit from CatCo, declaring that she was taking a leave of absence to pursue other interests. With Cat gone, Kara (Melissa Benoist) is now left to deal with her new boss, Snapper Carr (Ian Gomez), who thinks that Kara hasn’t proven herself worthy to be called a reporter. Meanwhile, Superman (Tyler Hoechlin) returned to Metropolis after helping his cousin defeat the two Metallos.
In the episode, it was revealed that Metallo (Frederick Schmidt) stole some kryptonite from the Department of Extra-Normal Operations (DEO) months ago, and he used this to his advantage in the fight against Superman and Supergirl. Metallo blasted Supergirl with the kryptonite, but Superman was able to defend her as he shoved the villain far into the distance. Later, two Metallos returned, and Hank (David Harewood) and Alex (Chyler Leigh) joined Supergirl and Superman to defeat the villains.
Supergirl visited Cat at CatCo and asked her whether she’ll miss National City. Cat told the heroine to be safe, and Supergirl told her to come back someday. Heading inside, Supergirl changed into Kara, and she was told that James (Mehcad Brooks) will now be taking over while Cat is gone.
At the DEO, Hank gave Superman all the remaining kryptonite so he could get rid of the lot. Superman bid his friends and Kara goodbye before flying back to Metropolis.
Next week, in the episode titled “Welcome to Earth,” “Wonder Woman” star Lynda Carter makes her debut as President Olivia Marsdin, and Supergirl goes into action as a threat emerges and an attack is made on the president.
In the episode, the president’s life is threatened just as alien vs. human rights issues heat up in National City. Supergirl and Alex are tasked to protect President Marsdin and bring in the responsible party. Alex teams up with Detective Maggie Sawyer (Floriana Lima) to investigate the case while Kara searches for Mon-El (Chris Wood), who has escaped and who she fears may be behind the attack on the president.
In the promo for the episode, the president walks into the DEO and is flanked by Hank, Alex, and Supergirl. President Marsdin says that the DEO’s mission is to hunt down renegade aliens. But Alex says that some of them are just hardworking refugees who are trying to stay hidden in order to survive. Later, Supergirl faces off against an alien with firepowers, and the girl tells her that she is a traitor to her people.
“It’s not us against them,” says Supergirl.
“Supergirl” airs Mondays at 8 p.m. ET on The CW.
