I just saw SD on todays SBS (Rehan will have it up shortly, patience 😛).
When they were asked if anythings going on between them...this is what they said:
D: Humare beech kuch valentine special hai hi nahin
S: Nahin kuch nahin hai, kyonki shayad aapne humein off-screen nahin dekha, hum bahut lar rahe the.
D: Hum baat hi nahin karte 😛
S: haa actually...baat hi nahin karte.
Then they start grinning and blushing.
S: humein forcefully baat karni parti hai....thanks to you (SBS)
They start off with their faces pretty straight. But they are actors after all. After watching the clippings of their performance, again their bodies n faces for very close a few times!😛😳
