1. either he just saw his dream girl
2. he saw that it's jiya....wish he knew, but he wouldn't have that kind of reaction if this was the case
3. thinks he saw barkha dancing.
i have a feeling #3 is it. it would wonderfully complicate the story. then he'll start acting nice with her but not letting her know that he "knows" she is his myster girl. barkha will suspect it at first but then she'll enjoy it and mistaken it as meaning her love has returned to her.
what will happen to jiya? hopefully naresh will be the one to come to the rescue. and who knows what rohan will do in the meantime.
by the way, barkha's sis is way annoying. her character really doesn't have many parts. she doesn't show any depth what-so-ever, vague dialogue alludes to some heavy history behind her stubborn meanness, but when that'll open who knows.
rohan is just awesome. and barkha, so realistic. i really love her.
