Knowing she cares for Duryodhan hence Karn doubt she is there to hurt him.
But if her plan is to hurt Uruvi , Uruvi has given her enough mixed signals
1) when the dasi comes to tell her that someone ( Karn) is here , Uruvi jumps to ask if the news is about the Pandavas aka Arjun
2) when Karn is losing at chausar she brings Arjuns reference yet again
3) yet she oogles at Karn in front of him
Bhanu is probably right to think she is playing Karn and she like the rest of world ( cause Uruvi hasnt ever put ger foot down and said she aint marrying Arjun) thinks and knows that she is marrying Arjun
They better come up with a solid plot next week - hopefully the trp s would reflect
