since only half truth is told.
its better they can solve the current track with MK being innocent and meera being affected by someone using the MK's name (it will be suitable if meera has one side love for mohan) - in this way MK can be no way responsible for the state of meera ).
end the sultan character by him not being the son of MK, meera, radhaji. so he gets depressed,
Also have a big scene of madhu yelling at him for wrong accusations of their family, getting involved in their family, giving him warning of not coming in life of her/RK and family.
so they can make him cant able to cope up with the anger from madhu and also not being son of meera die by suicide and end his character.
then focus on rishbala marriage life and then start the heroine track.
