nandita coz if he has to stay in show he need a girl who he have love interest where as pri is just frnd and other girls are already commited he dont like vrnda who is open still so left nandita.so as per of him to stay in show he needs to save nandita.he is clever so he will save nandita
He would surely save Nandita in that case. A friend is a friend but he sees Nandita (atleast for now) as a potential wife. So he would by all means save her!
