Superman & Lois returned on Tuesday with “Bizarros in a Bizarro World”, an episode that gave viewers some insight on how Ally Allston rose to power in the Inverse World as well how Bizarro ended up in Superman’s world. The episode also saw the origin of Jon El, the Inverse World’s Jonathan (or Bizarro Jon, if you will) as well the reveal that despite his seemingly benign arrival on Earth in “30 Days and 30 Nights”, Jon El isn’t a hero at all. Turns out, Jon El is a full-on villain, aligned with Ally Allston, and even someone who has killed in furtherance of her agenda. Considering that series star Alex Garfin, who plays Jordan Kent on The CW series, previously spoke about how Jonathan actor Jordan Elsass is a huge fan of Heath Ledger’s Joker from The Dark Knight, the idea that Jon El would be a villain isn’t a major surprise, but now Elsass explains how his own villain turn was inspired by Ledger.
