I think So too. She looks at it as a need that she can address easily. She has probably got experience taking care of her dad in past too and medical students are often just instinctually better able to attend to sick people’s needs. Like I don’t think any other family member would have stopped Virat from laughing. But Sai did it because she noted that the laughing was causing pain at the surgical site. She was very careful about looking at which medicine was for what reason. The sponge bath was just another in a list of chores. And she felt that a family member should do it rather than a stranger. I thinnk she was very respectful in the way she did the sponging with nothing romantic about it. It was Virat that was lost in her and admiring her doing her task in a focused way.
But I do want them to realize the gravity of these moments in their relationship. Sai should see that Virat wanted her to take care of him not anyone else. She was the first person on his mind when he woke up. Virat should realize that his health and welfare takes priority over all else for Sai. Even people stopping her physically didn’t make Sai budge. She still came, still did everything haq seh. And hopefully the magnitude of how intimate of a moment it is to take care of someone in this vulnerable state in hospital will hit them both.
