I think Vatsals character is going to last longer . He mentioned that he is an NRI and Mishtis friend in his own interview. And Helly confirmed she is a celebrity getting married . If they make them pair up then Helly would have not said hers is a guest appearance. Vatsals role seems longer . Also there is a doubt that he may be Nannu, Jas chichi is now happy with Mishti and Abir was already jealous of this guy after seeing Mishtis text. So makes sense to keep him around for 1-2 months till Mishbir realise that they cannot live without each other. By then I guess Baba 2.0 will be back 😆
