If zain gets upset hearing that that then I guess it's warranted that he reacts like that. I don't know if the cvs and makers of the show have forgotten this, but aliya and zain did promise each other that they would never hide anything from each other. Shayad, what they both meant was anything that was bugging the other, or if they had something they wanted to share. Dil ki baat share karna toh laazmi baanta hai.
I don't know, it's just might point view. 😊
P.s: It's 4 in the morning, and had this thought at the back of my head since I saw the episode and couldn't sleep until pointed this out. even though it may not make any sense.
