I read so many posts about flashbacks but I personally believe that she may not get flashbacks until she will meet Amar and something happens.For example both of them see someone beating someone in banaras or something like that sore that had happened to them when they were V and S. Or while roaming they might go to the same place where they were killed or hide the tape..Something that sort of a thing. This is just my guess.May be I am wrong. Or they may come to singh house and both of them have flashbacks together. Anything can happen in this shows.
