What does Ayesha want?!

she wants milind now.. and she can't see milind with prachi so tht's why she behind prachi....

Besides the fact that she's lost it? Well logically speaking (what am I saying) it's understandable... She is still under impression that Prachi is the evil-pretending to be kind-witch, so there's no way she could happily let Milind be with Prachi, no matter what Milind said. I would have done the same, maybe. Minus the crazed part, though.
