Seriously, I have no idea why people think Cabir might do something against Nandini or not take Manik and Nandini's side because he suspects her ...He, out of all people knows how you cannot just stop loving or stop yourself from loving you want -- Cabir wasn't being suspicious or will be against Manik loving her, he is just qurious as to how Manik will react to Dhruv's confession or what he himself will have to say about it since ... in fact, he will probably be the one to want to stand with them.Cabir is very perspective -- The only person who was shocked about Manik-Alya break up? Mukti.Dhruv knew and Cabir definitely knew -- from long time back about this ... That is why he was okay with teasing Manik about Nandini being drunk and how Manik knew it ...
