Bcoz probably the problms created by them denied any solution.
So may be the cvs, not being able to tie the loose ends are trying to end D3 itself forcing on the fans a happy ending (happy only 4 the cvs)
First by getting SwaRon married at a time when people think abt their careers and going out on dates and outings with their frnds.
Second by giving Rey a gf as if he has no other ambition in life save and except falling in and out of love. Swayam's Sharon's and Vicky's equation with Rey long forgotten.
"Even the cow is capable of climbing trees in a story" an apt phrase 4 D3.
