A few months later, Lionel was mentioned when Tess Mercer (Lex's successor) handed a file to Oliver confirming Lionel's involvement in his parents' death.

Tess discovered that Lionel had found Davis Bloome on the day of the first meteor shower and had initially believed him to be the Traveler. Tess was able to see Lionel's mistake from an objective point of view. She suggested that Lionel, along with Lex, was so busy fighting it out to become a worthy opponent to Naman that he was too blind to see the truth, that two boys had fallen to Earth that day that were destined to be each other's opponent: Doomsday and Clark Kent.
