Now, I think there is more to that dialogue. after yesterday's episode I think Simran would kick Sid out of the house. Earlier Kritika said a dialogue that 'one day would come when Sid won't have his own house and neither his sasuraal' so, most probably Sid would be kicked out from DD's house and Khurana house.
Anyway Sid won't agree for Kritika marriage with RV and this would lead to a face off b/w Simran and Sid and eventually she may ask Sid to go. i don't know whether his dad would be able to do anything, even if Raj says he would go with Sid, Sid won't allow it. RV - Kritika can surely manipulate Simran to convert all property to their name.
So may be Sid would have to begin his life/ business from the scratch, hence that dialogue.
What do you guys think?
