Her reason to avoid virat call is not ego. She is hurt by his actions. She has left his house. Toh obviously we cant expect things to be hunky dory. She picked up pulkits call n came immediately because thats how Sai is. If things were fine with virat, she'd have picked up. Even now the minute there trouble, Sai will go running to be by his side in hospital.
Why would Sai care about CN family except aai? Thet have not even treated her with the most basic respect. Phir bhi eventually Sai will be shown solving everyone's problems...
You penned it nicely Neerja
