Plot summary
Steven (Zach Callison) and Greg (Tom Scharpling) are in awe to discover that Greg's song "Comet" has been used as the basis of a successful burger commercial jingle ("Like a Burger"). The two debate what they should do with the $10 million Greg received for the jingle, mutually believing the best things in life to be free ("Don't Cost Nothin'"). Eventually, they decide to take a vacation to Empire City, and Steven suggests that Pearl (Deedee Magno Hall) accompany them ("Empire City"). Pearl and Greg are reluctant to vacation together, but Steven is optimistic.
In Empire City, the trio book a stay at Le Hotel, where the staff joins them in a song about the hotel's opulence and the fun they are having there ("Mr. Greg"). Greg asks Pearl to dance with him, but she refuses, abruptly ending the song. Later that night, while Steven and Greg are asleep, Pearl sings about her feelings for Rose Quartz and her jealousy for Rose and Greg's love, expressing her regrets and her inability to move on since Rose ultimately chose Greg and created Steven ("It's Over, Isn't It"). Steven and Greg awaken during the song, and Greg, lamenting that his relationship with Pearl is beyond repair, flees to the hotel bar.
Steven reveals to Pearl that he invited her along so that she and Greg could work out their differences. Getting them together, he plays a song on the piano, urging them to talk to each other about their feelings for Rose ("Both of You"). Once they have discussed their feelings, they are cheered by the hotel staff, and Greg is presented with the bill for their service. The three depart from Empire City; Greg and Pearl chat amiably while Steven happily observes that they are on better terms ("Don't Cost Nothing (Reprise)").
