Wts going on in his mind?
So it just strike in my mind,
isn't it possible that Aham dint find any other better way to Thank Gopi 4 saving his life by keeping His Ego, Hate for Gopi, His confuse State INTACT.
Matlab when he was talking to Gopi n saying Thanks his expressions were Genuine,at least I feel, nd next moment he react in his trademark angry style coz he dint want his weaker side, who got impressed by Gopi's bravery, to be showed.
Like Shelly mentioned He must be fighting with himself, So he does nt want to loose the battle with his innerself n may be this was just a tactic to assure his win, which wil soon going to change in a defeat when
He Wil be Ready to Lose Himself, His Ego, Attitude, Anger, Proud, Adamant Nature by Gopi's Selfless Love, Caring Nature, Gorgeous Beauty, Innocent Look and many more qualities.
Just My POV, Feel free to agree/disagree.
