priest has a chance to begin the ceremonies, Donna acknowledges to everyone that Sophie's father is present. Sophie tells her mother that she knows about her father. Donna realizes that Sophie invited them to the wedding for that very reason. The issue of Sophie's parentage is left unsettled, as none of them have any idea whether they are actually her father. Everyone involved agrees that it doesn't matter which one of them her biological parent is, as Sophie loves all three and they are all happy to be "one-third of a father" and a part of her life at last. Finally, Harry, who has made frequent references to his "other half" throughout the show, is revealed to be in a committed gay relationship. Suddenly, Sophie calls a halt to the proceedings. She isn't ready to get married and Sky agrees with her about not getting married. Sam seizes his chance and proposes to Donna in order to prevent the wedding preparations from going to waste. He explains that he loved her, even when he left to get married. It is revealed that he called off the wedding and came back to the island, only to be told that Donna was going out with another man (Bill). He went back, married his fiancée and had children but he got divorced. Surprisingly, Donna accepts ("I Do, I Do, I Do, I Do, I Do"). In the end, Sam and Donna are married, and at the end of the night, Sophie and Sky depart on a round-the-world tour ("I Have a Dream"). Finale and encore After their final bows to the audience, the ensemble performs a reprise of "Mamma Mia". A reprise of "Dancing Queen" follows, during which Donna, Tanya and Rosie are revealed wearing brightly colored ABBA inspired costumes. The cast ends the finale with "Waterloo", during which Sam, Bill, and Harry join the rest of the cast onstage in brightly colored costumes that match the leading ladies. The Dynamos and the dads often invite the audience to clap, dance, and sing along during the finale.
