it had better be a good reason

I am absolutely sick of the current storyline. What is the reason behind subbus anger. Cv keep saying bhhalla family and not a specific person yet he is going after Simmi and an innocent child. There needs to be a very good reason behind his family's death and I don't think cv have any such reasons to explain it at all. I really can't see any reasons to link them from previous episodes at all. Since shagun left seems they have put their entire energy in trying to make this plot work, which is a complete fail to me.
