Did You Know?


Kara establishes herself as Earth's champion after defeating her cousin Superman in a fight. This references a previous controversy in the comics, where the newly-reintroduced Supergirl was depicted as being stronger than Superman despite their gender differences. The explanation was that Clark, having been raised on Earth since he was an infant, had developed an instinctive and subconscious habit of restraining his powers in combat; Kara, who arrived when she was much older, did not develop this habit to the same degree and was more inclined to use her full physical strength, thereby achieving a physical advantage over her cousin.

At the end of the first season, Cat Grant reveals that she knew Supergirl's secret identity. In both her appearances in this season, she pretends she doesn't know. See more »


Clark Kent: [to Kara] Hey. You're never gonna guess who wants to see us.
[in costume, they arrive at Lena's office]
Lillian Luthor: Of course the two of you would make an entrance.
Lena Luthor: Unfortunately, this is her on her best behavior.

from the beginning of the "knowledge" of the DEO, we have been shown its great chambers that house many known aliens, with the abilities to create or reduce certain atmospheric conditions as needed. however, they just send mon-el away. um.... would it have been too hard to put him in a chamber for a little while, and introduce him little by little over time, to a level of lead so he can get used to it? i mean unless they do have plans of his return somehow in future episodes or alternate series. it became one of those moments that make you wonder, "why did they let me be smarter than the show."
