I have some predictions about who could bring Arjuhi back together...
I've ordered them the way it seems most logical..
1.) Shefali--- SHe will talk to Arohi and tell her that she knew about Arjun before but that she didnt want to tell Arohi because she could see the Love in Arjuns eyes for Arohi...
2.) Billu & Makhran-- They will realize that Arjun changed completely and will then try to convince Arohi...
3.)Arjun and Arohi themselves--- Their love brings them togetehr again!!
4.) Gauri Herself--- HOPEFULLY something will Go wrong and Arjuhi will get to know
5.) Raajveer--- He will start loving his wife and through this Gauri will forget about Arjun...Then she will tell Arohi herself what she did
6.) Mikheal--- His dad said that they will loose Arjun if he falls in love...So he will take the chance and bring Arjun and Arohi together again!
any other ideas??
