In the season two finale, "Nevertheless, She Persisted", Lillian visits her daughter in her company's building telling her that despite her malevolent acts, she wants to make the world a better place to live and promises to commit herself to improving their relationship, even telling Lena that she could be a Luthor who can save the world. Kara and Kal-El come to their building for help to defeat the Daxamites.
