Didn't KD wonder?

But, didn't KD wonder why Kiya had come on the dance floor beside him and was trying to get attention from him. I think he got caught in the moment and pulled her into the dance. I wished they had shown a scene where he was thinking of why Kiya...the person who hates would do that. We all know they have feelings for one another...but KD was not drunk or anything (he was drinking juice at the bar). I want to see a scene where one of them brings up the dance. I also want KD to find out through JJ that Kiya did not go with Kunal
