Tonight’s episode of Supergirl, titled “Falling,” will see Kara become infected with red Kryptonite. If you thought the green stuff was bad, just wait until you get a load of what this stuff can do.
“It just takes away her inhibitions, it makes you speak the truth, and sometimes that is not always delivered lightly. She becomes dangerous, and in a way red-Kryptonite Kara is the villain of the piece,” executive producer Ali Adler told us at PaleyFest LA 2016.
Red Kryptonite essentially turns Kryptonians into one of the bad guys. They’re full of hate and rage instead of the hope and light that makes them a hero. It also makes Kara really, really cruel to her loved ones.
