Here's what i think will happen:
Sameer will completely repent all his past behaviors and will change after saumya's death, but no one in the family will understand it. they will all, including pari, hate him for killing saumya, much like rani hated prince for killing raj. So Sameer's agnipariksha will be now to constantly prove himself to his family and face all the hardships and bla bla bla.... and taking care of everyone until they realise that he is good.
what say?
