Then only what Guriuji said would be justified.
Because all the problem of this killing Madhu started from what he said about Ballu's destiny and Madhu's destiny.
And the real story too started from there. Paddy escaping with trishna, landed on a film set, Madhu born in a film set and all. Both these are related.
Also in previous interviews of DD, she always said she will agree to do the film on her mother's request. So Padmini knows Madhu doing a film and getting fame will be the fall for Ballu. So Paddy might ask her to do it to make the whole family safe.
