1. They can't link AR. It leaves Sid and Shilpa to bite the dust.
2. They cant link AS or SR because that destroys the two year relationship that AR shared.
So what are they doing instead? Milking the situation! They're giving little glimpses of ALL three couples whereas we know its not possible for all three to form. They know that as long as they don't start any COMMITTED romance track, fans of all 3 couples will continue to watch.
But that leaves me to wonder, how long can they keep that up...
