Things don't go smoothly and then Rudy comes in and finishes the model. Mike goes off with Rudy. Later, Mike is having a hard time with a composition for school. Flora tells him to ask Sam for help, but he goes to Rudy instead. Rudy intentionally gives Mike bad advice hoping he will then turn to Sam.
