(Adventure Comics I #250) - The Kents watched TV at breakfast, and a message came through a time barrier sent by Inspector Edaw-8 of the 30th Century Scotland Yard. Criminal Lorac had traveled back in time, seeking cobalt, which was outlawed in the 30th Century, to create a doomsday weapon. Lorac knew Superboy's identity, and was disguised as one of his friends or neighbors. Superboy went into action, and suspected a number of people, including Pa, who was acting funny after a bump to the end, and Professor Lang, who was jittery about an upcoming science talk. He eventually uncovered Lorac impersonating Lana Lang, his suspicions aroused because she hadn't once tried to expose his identity, and learned that Lorac was Lana's distant descendant.

(Adventure Comics I #307) - The Langs went away on a trip, but couldn’t take Lana with them, so they arranged to have her live with the Kents until they returned. Clark reminded Lana of how foolish she looked the last time she tried to prove he was Superboy, causing her to instantly break her recent promise to stop hounding him, and making her more determined than ever to expose him as Superboy. Lana exposed Clark to red kryptonite, and she soon realized Superboy had lost his voice. Clark fooled her into thinking he could still talk until the red-k wore off by using a telepathic helmet gifted to him as a trophy by the aliens of planet Yhalla. Clark thought she’d gone to far by exposing him to kryptonite, and decided to teach her a lesson. Clark stumbled into the police station and told Chief Parker he’d lost his memory. Parker called Lana to pick him up, and for a second she wondered if the red-k gave him amnesia. At the mention of Superboy he confessed to being the hero, proving his powers by shooting himself with a gun at the police station and lifting a safe. The gun and safe turned out to be props from a recent police show, so Lana was now convinced Clark wasn’t Superboy, but was a danger to himself. YHe jumped off a building, dressed as Superboy to show he could fly, but used his super-breathe to fly a clay figure of Superboy under him, catching him and dropping him off at another rooftop. Clark pretended to regain his senses, and Lana reasoned he’d temporarily snapped due to stress from too much school work, and made him promise her not to get the foolish idea that he was Superboy in his head ever again.
