I agree that there is no explicit direction how to stop the video! Samay chose to do it a particular way! So Maya has nothing to do with it! Is it as simple as that?
I am sorry but i really don't understand your point of argument. When did Maya say to kill Prem exactly? And Samay has his own brains i said he took the opportunity to kill Prem and degrade Maya in Arjun's eyes so that ArYa are separated.And as far Maya is concerned about using Samay. Then yes it is definitely wrong. And now Maya is going to learn her lesson into using Samay. Because now Samay will trap Maya. Maya will face the music of using Samay.But Maya did not want Samay to kill Prem. Thats what this message means.
Maya knows how Samay can be inspired to do dirty things for her! She saw how violent the person could turn out to be! Did she see a live demo of 'cuting his finger'?
In this context, she has sent a subtle message making a request in the name of his love for her & at the same time putting Arjun in front of him! It is a clear provocation & instigation! And the jealous mad dog showed his loyalty to the master!
Her subsequent reaction & insensitive feeling upon hearing Prem's death like 'no matter how many people die, no one can separate Arjun from me', puts her in the same class of Samay! Both can do anything for their love! And Maya used Samay knowing him well!
