How do we know it's Mandar's call that interrupted ??
Also I hope that if it is then pallavi either silences it and doesn't pick it up or if she does then puts it on speaker in front of Raghav and asks why he has called and if he gives some answer indicating he is expecting chit chatting then she shuts him up saying it's late and I have to go be with my husband ya it's late and I have to sleep.
