Clark starts experiencing "vision problems" which of course mean his "x-ray vision" is starting to develop. Meanwhile, prominent figures such as Lex Luthor are committing crimes such as bank robbery. It turns out a girl named Tina, who idolizes Lana, had soft bones as a child and was "cured" by kryptonite radiation: she now has the power to alter her physical form (and, conveniently, her voice, hair, and skin) to look like anyone she wants. She inadvertently killed her mother, and now plans to kill Lana and take over her life. Clark, with his x-ray vision, is the only one who can make out Tina no matter what form she takes due to her irradiated bones. He confronts her as she tries to kill Lana, and despite Tina wearing the kryptonite necklace she took from Lana, Clark manages to defeat her.
