Lakshman went to vanvas with ram for him but here sid was the reason raya separated still ram raised kush as his son and gave him the kapoor name infact i am damn sure ayesha would have aborted kush if ram didnt take the responsibility of him when sid went to jail for 2 nd time he asked ram to take care of kush
Ram has all the rights on kush more then sid just because he gave birth doesnt make him father
I hope sid wont fall for this stupid trap and question ram even if he does atleast kush should stand for his ram dad
Ram has done more than nedded for sid he did give him another chance and allowed him to stay in KM
