Arushi holds the key...

A thought just came to my mind that I'd like to share...Was Arushi present when Angad had come to their house and said to Pratigya that he made a mistake by letting her go without touching her?! If she was then she should tell Krishna about this. Though neither Pratigya or Krishna are showing Arushi that they are experiencing problems in their marriage, so how would she know to tell Krishna the truth about Angad?!
