The couple being married, and loving each other makes everything look a lot less sinister.
And the TRP audience tends to watch peacefully even if the hot water is tossed at the female lead or she is made to walk on actual glass.
So the Rishbala eps may have TRPs affected by the matches.
It would be the reason if TRPs do lower.
Show the female lead in more anguish, and so long as there is no third guy that she is even unknowingly not keeping at a distance, TRP audience sympathy for her feelings and hopes for the couple to stop fighting and reunite will work in favour TRPwise.
Without scenes that TRP audience might favour, TRPs will fall worse in contest with IPL.
But the other guy's presence - if increased - could have a repeat of the Mukund effect all over again.
