I've not noticed it before. But with Sai I've noticed it a few times, one during the chudail scene and the another very recent one when he was tending to her when she was hallucinating Vinu.
There was one in preleap... in police station... during Samrat death track.. I dont remember the exact situation though.
then post leap when V was beating Gulabrao, Sai held his cheek and he stopped.
Kal there was in LW when both Satya and V were at each others neck.
And this is the lastest ...
Probably there were more... ๐๐ผ
