Sanam reached the end of her vengeance. She looks triumphantly at Sanam2, refusing to acknowledge her as victor. As she holds the magic ball that holds everything Sanam2 holds dear, her magic powers.
Do not think you have won... It does not matter that I did not complete my vengeance. Leaving you alive without your powers is your punishment.
And everytime you stray towards evil, another will come to defeat you. Until then you will live this punishment of a life...
Sanam backs slowly to the cliff edge, her thoughts beginning at the point she lost Aahil. But she swiftly changes it, to remembering the moment they were meant to be, their love, their feeling of togetherness, the passion.

Then she remembered happy moments with Seher, her long lost sister, her other half. Then moments she met and spent with Shaad, the man who saved her from a certain death, and who brought her home.
And then she remembered their deaths. And with a resigned peace, she fell off the cliff, the magic ball with her.
And far away, a baby is born, to a loving father, with a lucky mark on her neck,the sign of infinity. The happy father names her Mahira.
Sanam2 is at the point of devastation. She does not want to live without her powers, and she moves to jump off that very cliff.
But a man pulls her back. With a showy bravado, an unquenchable curiosity over her. He wants to save her from her point of hopelessness, promises to fill her despair with love. Drops on his knees right there and proposes.

Cut to 20+ years...
Ibrahim mansion looks creepy in the moonlight. Sanam2 is now Khan Begum, (badi bangle wali .. LoL) and she lives in splendor as a famous superstar Naseef Khan's wife. Lateef and Khala have moved with her too...
As Khan Begum sits, dressed in riches, she is seething with ill feeling. Sanam took away my most precious possession, my power. She says she will return, but I am not alone. I have my two children, and she has no one. I will not be defeated !
Her feet are burnt and scarred, and she looks like she has lived with a lot of physical problems without her powers. But she is hauntingly beautiful, like a reclusive Queen.
Precap: A buff muscled man is shown in silhouette, and the bespectacled Mahira arrives at the spooky looking Khan mansion.

Just kidding... it was a very intriguing episode.
Darn it but somebody really good is at the helm of this leap.
