Awesome post baby.
Amongst the three of them, Sid is in a much better position to analyse things and he is the one who understands the other two perfectly. He is the one who has seen these two at their vulnerable best and he is the one who knows how hard they are trying to adjust to the situation. And he has matured a lot during this learning phase.
Yesterday was a sincere effort on his part to make things right between his wife and his big bro. Kudos to him for that. Riddhima needs reassurance from Sid - he has proclaimed his love for her. He now has to give her all that she needs from that relationship - a husband, a friend, a confidante, a philosopher and a guide along with a assurance that he knows she belongs to him now and whatever happened in the past shall remain there and not affect their future.
For Armaan, Sid somewhere feels guilty to be responsible for his present condition. Humour helps. And by involving Armaan in his life with Riddhima he wants to assure him that he will still be a part of their lives..... Its only when Armaan really moves on will Sid be able to let go of that guilt. Riddhima too. I am hoping that Shilpa will be that healing touch to these beautiful yet troubled souls.
Love ya,
Ash
