Plot
Sam is playing baseball when he sees Heidi MacAvoy in the crowd. He tells some kids after the game, and they are freaked out. Heidi walks in on a kiss between Sam and his current girlfriend, Jennifer Leguizamón. She screams. She tells Sam that he said that he said that he and Heidi would date if she got back to his world, and there would be no dating in between. Sam says that he doesn't remember that, but Heidi just leaves. She calls him later and tells him that he can express his feelings towards her by singing to her at an upcoming talent show. He sings Intermission, a little-known Big Time Rush song about wanting a pause in a relationship. She kisses him afterwards, outside, in a thunderstorm. Sam explains the meaning of the song. Heidi leaves and says that her whole life, she will be waiting for the day that that intermission is over.
