I feel virat was apprehensive.. so many bitter words had been exchanged between pakhi n virat .. so he was pussyfooting.. he did not want to get in any bahas with pakhi .. since he had an upcoming issue to sort with sayi .. his mind was on sayi ... so he just picked the tea āļø and then decided to drive the message to pakhi . That now bear the 2 of us together .. so he said give me another cup .. he had come to get tea for sayi only .. but he used that moment to reinforce that I am taking the cup for my wife ..
I think you are write, he did not want any argument plus think he did not want to have any conversation with her. I guess the eye lock was a reinforcement of the fact that Sai is a part of my life and will always be learn to deal with it. His mind was indeed on Sai.
Additionally, this is the first time I guess Virat and Sai have argued over Pakhi. So he needs to see what's happening around.
