ok guys me have a theory regarding PL's presence whenever neev says he will help michi.....inspite of their tryig milind does not get his memory back and ayesha decides to speed up the wedding seeing this Pl tells prachi to give up and marry neev since he is her friend and also loves her.... only then will prachi reach the mandap in dulhan attire since dadi is busy with kyunki they need some eldely force to make prachi agree ......
