A rehearsal turns tense when the group plays a new song called 'That Night.' Zayn and others say Jason named it out of jealousy; someone vows to teach him and calls him 'the son of the help' for defying his boss. They expect a weak opening, but the chorus delivers intimate lyrics—rejection, tears, drunkenness, a breakup, and "you didn't reject him; he hurt you." Listeners wonder if Jason still likes Abby. The episode closes with the group confronting the implication and asking, 'What happened between you that night? Why would he write a song like that?'
