gayathri devi

who is gayathri devi and why is she following

Please use the Help Desk for such queries. But I'll answer your question here:

She is someone who surfaced late last week, and is someone who knows the Jagirdars, & they know her: they are obviously not on good terms. So when she sees Yuvraj w/ a girl, who she doesn't know is his wife, she thinks there is something fishy going on & decides to follow them. That's what happened from the spot where Neeraj was thrown down the ghat, and she followed Yuvraj, saw the car sway, thought he was drunk & followed it until she got to the car. From what they showed today, it's somewhat obvious that she took Sandhya & went off before the car exploded.
