Okay I've heard two plots for this episode, which is true?
Plot 1: Griffin comes back and decides to date Sam instead.
Plot 2: All the air in the apartment breaks but Spencer makes an air machine for his room, so everyone in the apartment has to stay at Carly's place. That includes Griffin.
Which plot is right? And if both of them are wrong than what's the real plot? And what's the sub-plot?
