Synopsis:
While his foster parents leave Smallville for a week, Clark pretends to go with them. Then as Superboy he offers to give Lana a chance to prove herself trustworthy by protecting his secret identity. Superboy disguises himself as Tommy Lang, Lana's cousin. Lana must keep the secret for a week to prove she can be trusted with Superboy's real secret. Lana fails, as she makes five errors that would expose Superboy's secret. Her last mistake gives Superboy's identity away to some crooks. Superboy abandons his Tommy Lang disguise, hoping that now Lana will finally give up her quest to learn his secret.
