Isnt that what we saw yesterday. When Naina realised her speech was stolen, she didnt know what she would say on the stage. She had nearly lost her hope of giving a good speech, forget about winning the election . But that one look at Sameer did the job for her. Even when the whole world along with her knew that she was at loss, her man had hope in her. He trusted her to bounce back with even more confidence. His smile and his affection gave her the courage to calm down and think sensible. The way he signaled her to calm down was too good.
The "LOVE OF POWER" had literally destroyed her peace and had made her believe she had lost the battle even before it started. Well she and the world was wrong because she had something powerful and magical with her - yes!! , its the "POWER OF LOVE".
There is a saying that "When the power of love overcomes the love of power , the world will know peace." That scene translated how LOVE OF POWER was destroyed by POWER OF LOVE. The smile he gave her after she gave that beautiful speech was that of a MAN WHO IS VERY PROUD OF HIS WOMAN.
