“Strange Visitor from Another Planet” (S1 E11) A White Martian comes to Earth hunting J’onn/Hank, bringing back painful memories of a Martian holocaust. Meanwhile, Cat’s son comes to town to become Kara’s love interest. Luckily, he's already married to her.
“Childish Things” (S1 E10) Winn’s dad AKA the Toyman appears at long last. Was it worth the wait? Knowing this show, do you even have to ask?
“Blood Bonds” (S1 E09) The reset button gets pushed on Cat figuring out Supergirl’s secret identity, Non and Astra's evil plot goes nowhere, and there's an abnormal amount of people getting tied to chairs and beaten up.
“Hostile Takeover” (S1 E08) Supergirl’s evil Aunt Astra is back, and she’s brought along a much more verbose version of Non. But the true villain is whoever decided we needed another lighthearted Cat Grant-centric plot.
“Human for a Day” (S1 E07). Supergirl loses her powers, but—surprise!—she’s still a hero without them. Meanwhile, the job of fighting this week’s obscure DC villain falls to Alex and Hank Henshaw, who finally reveals his true identity.
“Red Faced” (S1 E06) Lois Lane’s dad comes to town and wants Supergirl to fight his idiotic-looking robot, the Red Tornado. Luckily, she’s angry enough to do it, but not half as angry as Red Tornado fans.
“How Does She Do It?” (S1 E04) The episode they didn’t want you to see last week finally airs, and maybe it’s still a little too soon? Also, Supergirl faces her own cut-rate version of the Unabomber while watching Cat Grant’s son.
“Livewire” (S1 E05) Thanksgiving is the third week of November in National City, apparently, as Supergirl takes on a villain from the DCAU who becomes her lamest foe yet.
“Fight or Flight” (S1 E03) Supergirl reveals to the world that she’s Superman’s cousin (which the world somehow didn’t already know) and becomes the target of an old Superman foe.
“Stronger Together” (S1 E02) Or, “Supergirl Relearns”. Supergirl causes an ecological disaster and realizes she sucks, so she enlists her friends to help her learn how to be a superhero... for the second time in as many weeks.
“Pilot” (S1 E01) For the first time in a long time, we get aspects of the Superman mythos onscreen not weighted down by angst or failed attempts at achieving Christopher Nolan and/or Frank Miller levels of grimness.
