I feel that slowly the nameless will be able to convince everybody in the house except DM that she is Subhi and everyone will turn against Santu who they will feel has usurped their daughter's/mother's place.....DM will be the only one who will stand by her which will make their bond grow even stronger. It will be ironical if it happens because previously everyone in the house wanted Santu to stay but DM was willing to let her go albeit for her own sake and now the roles would be reversed with only DM being Santu's support.
