Who informed Mauli???

Whilst everyone is pondering as to why Pari, Kunal, etc are at the airport I myself am wondering how Mauli found out Ishaan was leaving and was at the airport. Who informed her? It couldn't be Ishaan himself. Poor guy was too heartbroken so I think it would have been too much for him to even hear Mauli's voice. Yes, Dadi spoke to him so it's possible for him to have told her but I think she would have kept it to herself for selfish reasons or already mentioned it with all the dialogue she had today. I doubt the kids knew either. Ishaan didn't even inform them as to where he was taking THEM so ditto as to informing them as to where he was going. That leaves Sandhya. The episode ended on a mini cliffhanger. Everyone was waiting for Mauli to open her mouth to respond to everyone's pleas but I don't think she's even gonna get an opportunity to do that. The writer is gonna extend the cliffhanger a little more. Sandhya has got a bone to pick with Mauli so I think just before Mauli responds Sandhya is gonna ring her up to give her a piece of her mind about breaking her son's heart and in the process inadvertently inform Mauli Ishaan is leaving. In the same way Mauli left Ishaan's house without a word upon being called by Radhika Mauli would then dash off to the airport still without informing as to what her decision is. Kunal and Co would then tail her(he's got previous form)worried as to what happened and where she is going so hurriedly and they too would wind up at the airport. That's why the whole confession at the airport thingy. If she was choosing Kunal she wouldn't even need to confess her choice at the airport...it could be done so much better at the Malhotra apartment.
