When news broke over the summer that Supergirl Season 2 would be involving Lex’s sister Lena, it seemed likely that the show was either building to the introduction of Lex as a Supergirl villain or using Lena as a Lex surrogate.
After all, the show added Superman into Season 2 when he had previously been ruled out; who was the say that the show wouldn’t bring in Lex in the wake of his lesser-known little sister?
But no, the show can still have Lena’s cake while icing it with a deepening bloodline.
One of the biggest, baddest, and scariest villains of DC Comics is Lex Luthor; even folks who have never picked up a Superman comic book know him as the Man of Steel’s greatest enemy.
