Tom comes up with a brilliant idea for an item his team can sell for Business Day. But because he was busy doodling, Tom accidentally gets himself switched to another group. And Tom's sister Delia continues to be grumpy, but now she has a key to her bedroom. What is she keeping locked behind that door?
