what was the point of this dp track

I didn't get the point of this whole DP track....why did DP return after so many years to make Dutta more angry when his son was finally happy with his life and was trying to settle down he came and turned Dutta's life upside down...why?????😕...and why does Nakku had to tell the whole story of Dutta's parentage infront of his whole family.😡..making a fool out of him...cant she just stop him and tell him that this man is his dad...now the whole family knows that he is not the son of DSP ....how come no one was surprised that Nakku knows the the whole truth abt Dutta's past life and no one else does...😲

I feel like either they have changed the writer of this serial who has no knowledge of the earlier episodes or they have all gone crazy so they r introducing stupid tracks just to prolong the serial 😡
........I am seriously losing interest in this serial...and this way they will lose their viewership.
