It all starts when Lisa makes a cup of cocoa from a packet in the break room. She doesn't know that it's Paula's and that it's the last one. So when Paula comes looking for some chocolate, there isn't any cocoa. But she does find a chocolate cake in the fridge with Lisa's name on it. Paula decides that, since Lisa took her cocoa without asking, she will eat some of Lisa's cake without asking. When Lisa finds out, she's upset, because she was bringing the cake to a friend's house for dinner that night. Now, since it's got a slice taken out, she can't. Meanwhile, Paula asks Miguel to test her new formula for protecting garden plants from hungry critters. But the formula tastes terrible and burns his mouth. He decides to “get even” and put some of the formula on her cake. Ultimately the team learns that “getting even” is not the same thing as “being fair.” It just makes a big mess. True fairness and forgiveness are so much better.
