I agree Sara is the ideal Sadhna. But they are killing Sadhna only, not Alekh. There is no question of Angad leaving the show as of now. After Sadhna dies during child birth what turn does Alekh's life take without Sadhna/Sara? How will the storyline continue with the threesome. Will they show Alekh dying too after Sadhna? How will they live without each other?
