Sometime later she met Olsen again during her work for the website. For one week, she was at the side of Sebastien Mallory, the junior-executive of LexCorp and personal enemy of Olsen.

At Cadmus Labs Sullivan found out that every planet which the Dalwythian choose to be their party-host didn't survive this experience.
Later, Sullivan and Mallory traveled to his apartment in orbit where she found out he's trying to control the world with the Superman Videogame. Together, Olsen and Sullivan stopped Mallory.
