Now that it is sure that Nia is leaving and we will get the leap, I fear Sid will face another promise needed to fulfill. I think the goons were sent to beat Roshni by Payal. I think now Payal will create some issues leading Roshni's complications in her pregnancy to worsen. Roshni might face serious issues where Sid will be forced to choose between his life and his child. Of course he will choose Roshni. But before Roshni and Sid get into that situation, SidNi will have a conversation where she will tell him, "If anything were to happen to me, promise me you will save our child first." She will force him to promise that he will protect their child over her. This will lead him to choose their child over Roshni as he fulfills his promise. It will be his dilemma but that will lead to Nia's exit. Then we can see Sid grieve over Roshni and take care of their son. When the leap takes, place they can show SidNi's son looking at his parents picture. If Neel and Ria are shown alive still, they can show how they were the ones to take care of SidNi's son as their own, but telling him about his real parents. The villainmight be an older Ayesha who will try to claim her due as the elder Khurana (even though she is adopted).
