One can also imagine that Jon Cryer’s Lex Luthor will somehow be tied to the main villain of this season, Ben Lockwood, a.k.a.
Whether Liberty is already in communication with Lex or they’ll form an alliance later this season, or even if Lex has his own separate plans in motion, given how much Lex hates aliens and his past with Superman, it wouldn’t be wise for Supergirl’s protagonists to underestimate him.
Agent Liberty had been working with Mercy and Otis Graves, both of whom previously worked for Lex, but they were killed in the most recent Supergirl episode, “Ahimsa.”
Agent Liberty, who’s leading a violent movement against aliens on Earth.
