The holi wala sequence is one of my favourites too! Amruta mentions the word ‘pyaar’ and the way they look at each other! And Raghav’s hand accidentally touches Pallavi’s and neither of them take it back, for a moment they are lost there.
Also when pallu comes back home, and sees red on her face in the mirror. You could just see there how much she misses the colors in her life even though she kept telling everyone that she didn’t want it anymore.
There have been three instances Pallavi is shown in such light, one the holi wala day, other two- the chalka re sequence where she sees herself as a bride and one where she’s looking at her wedding album and crying, in the very initial episodes.
I love how they included all these in the show rather than showing Pallavi totally out of it and completely happy with her current life.
