Just as Clark and Lana are making progress and he finally sums up enough courage to ask Lana out on a date to a local festival, an old flame rekindles when Lana's former beau, Whitney Fordman, returns from the Marines to make up for lost time. But something is wrong with Whitney for he isn't himself, and Clark sets off to find out what's wrong and why Whitney doesn't remember some things. But the big twist is that the real Whitney was killed in action in Indonesia, and that the meteor-rock shape shifter Tina Greer (from the 'X-Ray' episode) is impersonating Whitney to get romantically close to Lana. Soon, Clark finds himself in a bind then Tina traps and immobilizes Clark in his storm cellar tied up with Lana's kryptonite necklace, until help comes from of all things... the spaceship. Meanwhile, Lex confronts Helen Bryce about her employment with Lionel and questions her motives for being in Smallville.
