he is loosing it completely ..someone needs to help him when he needs help, hismother questionable, so still nandu feels she can do that..and this is the reason she is helping fab 5 ..not to help them on putting harshad down,but to help manik.
odds...to fight his inner demons and come out as a winner... right now he is in an emotional turmoil, which no one can understand...only she can ...she chose to stand by him to let out his pain, when he faltered...she will become his strength to fight his emotions..
I guess many of us, have been upset for the reason that Manik is doing and hence we have his guardian angel next to him no...she stillloves and cares forhim and want to see him as a winner and hence will do everything...sometimes bending a little for the person you love is not wrong...this decision of hers has not made her less independent...she knew Manik needed her support this time, and if her this little effort could help him, she will do that...she still trusts him..
PS : how much trust she still has on him, she searched for dhruv when harshad was drow ning that means she remembers everything on being talli, so the kiss and head on his hands and so hot , all she wanted to do with him hehehe😆
