Ok, so Sindura completely knows that Vidya would never ever cheat on her husband. There isnt' even a doubt. If she would have used her brains properly she should have found out what exactly vidya was doing instead of just the fact that she's entering a house, who's door was opened by a man. Seriously ever heard of a door man Sindura!!!!
Not that i'm saying Sindura should win or anything, but hey this turned on her didn't it. 😉
