2x1 - The Suite Life on Deck

A microchip with secret information on it goes missing and the twins help a spy recover it. Cody gives the chip to Bailey, telling her to hide it and not to look at what's in it, but Bailey looks it up on her computer anyway. When Cody finds out that Bailey ignored him, breaking her promise, he has mixed emotions. Bailey kisses Cody on the lips as a way of telling him he can trust her, so he forgives her.
