Supergirl spends the next few days protecting her secret identity from Superboy, Lana Lang, and even Krypto. She also keeps her existance a secret from everyone, but the Kents. She performs her task well, but one evening she returns to the Kent house through a window instead of the secret tunnel. Fortunately no one sees her, but it proves she is not yet skilled enough to completely protect her identity. She returns to the present, disheartened that she is still not ready to be adopted.
