Is Kate Alive? She certainly is. Everyone thought Dupli-Kate died in episode 5's barbaric showdown between Rex, Dupli-Kate, and Shrinking Rae and the nefarious Lizard League. Established fans, though, will already know that she survived that encounter, with Dupli-Kate's original form not taking part in that ferocious fight. Tired of dying over and over again, she let her clones duke it out instead. With all of them perishing during the battle, Dupli-Kate was able to fake her own death. It's unclear how, when, or if she'll reveal she's alive to her fellow superheroes. For now, we're sure The Immortal is overjoyed that she's still around.
