From 22nd March episode, Daya might realize that MLS absense is another one of his tricks to turn his son(s) into "MLS". I think this became obvious to her once she saw how parnav forcefully overruled sneha decision to bring their office work home. She's probably picking up on the fact that her sons are inadvertidely becoming what their father ultimately wanted. Also, the show uses a neat trick of now playing MLS background music on parnav(at the end of the episode), a nice touch.
