I feel its Sid's subtle reply to both debo and kash 😈..
Kash called her fake and debo compared her with her attention seeking dog about which sid was specially enquirung from Shehbaaz in that usud .
After this we can see Kash entertaining them and debo doing head massage while Sid himself holding Sana in his arms and sitting with her like prince and princess ..
Its like sending silent msg to all what she means fr him and how its not one sided ..
Sid does many things with his actions which is difficult to decode ..and these r not shown in epi so all feel sana is desperate fr his attention when truth is Sid shows equal desperation..at one point she qas leaving hand but he tightened the grip and dint let her go ..
