 As for who the worst is, Geoff names Cory as the worst for his attitude and the fact that his projects (including the platform for the stove) were hazards, while Gail picks Matt as the worst for letting his standards slip and leading the group project to what Geoff describes as "the worst project he's ever seen".Andrew ultimately sides with Geoff, and Cory is named the worst for the episode.For homework, Cory must open up about his attitude to Andrew as a measure to keep it under control.
