whom did Arnav looked at? - Page 2

It was only the last scene where he looked at Khushi. He eyes were mostly on La today due to his concern for her.

He was looking at LA. 

both.. but there was that once distinct spot when he kinda smiled looking at Khushi dancing (made her falter) and La saw him staring at Khushi.. further hammering the point that  ASR really cares for Khushi.. thus making her upset..

he was mostly looking at la - but in one second he looked at Khushi - that's when La left the dance floor. I didn't really get confused then.

There is an excellent account of what happened in those few seconds of "looking" in the thread below by @tanthya - Do read it.
