"accidentally" run into them after convincing her that Titu is still in love with her and he wants to help them get back. They return to India with Pihu; Sonu is happy to see a bothered Sweety after witnessing the closeness between Titu and Pihu. But Sweety reveals to Pihu that it was Sonu who broke Titu and her up in the first place and that Sonu is using her. Titu learns the truth and turns Sonu away in anger. Ghasitaram and Lalu volunteer to sort the situation but Sonu interjects saying Titu should decide for himself. Sonu helps prepare for the wedding but during the garland ceremony, he makes a final attempt and gives Titu the ultimatum again to choose between him and Sweety and walks away from the wedding in tears. Titu, in a fit of epiphany, reveals to Sweety that this is barely the second time he has ever seen Sonu cry, the first being three days after his mother's death when they were thirteen; his tears show what Titu means to him, and Titu firmly announces that if it is between Sonu or her, it will always be his best friend. The scene switches to Sweety standing in the mandap and coming to terms that her malicious tactics cannot always work. After the narrow escape, Sonu, Titu, Ghasitaram, and Lalu are seen sitting and drinking by the pool, whilst Sonu discusses his own marriage plans, to the disgust of others.
