Acc to yesterday scenes, DurNi may again doubt on Sid's Character, like having an extra affair or something, when he tried to help Bablu chacha and his wife. But chances are very less in my POV, bcos ,if not DD , atleast Roshni would be strong on their trust. Whatever Sid is doing is wrong only, but they should knew by now, that Sid would do anything n everything for his family only and get to know his side of the story, if he didn't tell them, they should find somehow,like Rose said in her post... that's what any wife would do normally.
