You're right. They should give something from sai's side. Maybe showing that she called but pakhi received so either sai didn't speak or pakhi hid it from everyone.
Or hospital calling at home but someone purposely not informing virat. Then, it'll make so much sense that why she's so mad at virat and that he didn't come looking for her.
Even now, i think she did the right thing because v supported a criminal etc, but showing something solid Will give a strong and logical reason for sai's side of story. Something more practical.
But, they might not do it, as it'll make pakhi too negative😭
If they actually show sai contacting but pakhi or someone hiding or sai calling but not being able to talk to v, then it'll be safe to say that at least she tried to contact but it went wrong, so she's not at fault.
Otherwise, the situation will be in virat's favour and how sai did him wrong😭
