I think if we go by the timeline, many things would not make sense. Like Sofna said its exactly one day after the wedding and Lav is back with Su and that too with a varmala. We also can't overlook Lav's dialogue thi Div and Dri's to Shi as mentioned by Indu.
So I can safely say that makers made a total hash of the timeline and expected us to only enjoy the drama and the romance which is shown. And moreover with so many characters to juggle, timeline took a back seat. 😆. And I think there are more new characters to come.Waise looks like, being possessive is a typical Shergill trait. Not only Ra's epic "Mrs Rakshit Shergill" but Shi also gave a glimpse as he corrected Su, when he addressed Div as "bhabhi D ". Shikhar asked him to call her as "bhabhi ji" not "bhabhi D". 😆🤣
