They won't introduce new lead...
So how sai and virat will reunite...in kd no one was harsh with emon....they welcomed her and she was pregnant... here bk gang will be rude with sai and pakhi will become revengeful when she know virat was loyal to Sai....and virat will be standing high in the Everest with his ego complex....whatever twist it may happen...these will happen for sure....
Will remarriage happen...the only way by which sai living in cn is justified...
