The confrontation between Shammo and RK was good. RK's dialogues are wacky. RK did a good job of opening up Shammo's locked brain.
How can one understand a person who is a closed book and gives confusing signals. Madhu is not some mind reader that she can understand RK, as he is always poker faced in front of her.
Some people expect to much from Madhu, the only reason RK is able to understand Madhu is because she can not mask what she feels. What ever she feels that shows on her face.
RK is poker faced, can not tell what he is actually feeling.
Shammo's senses and reasoning are blocked because of his hatred for RK and love for Madhu.
Why should Shammo give RK another chance, when RK has not proven to him that he is good person.
