I have not seen the preview, but after reading the preview about Dev discovering marbles on the staircase, it made be think that these people (Dev's family) have not cleaned their house since NT's death. 😆 😆 Dirty People!!! 😆 😆
How else can anyone explain the discovery of marbles now, that too so many days after NT's death? If if was just a random case of one or two marbles, we could have dismissed that those got lodged inbetween the wedges on the sides of the staircase, but Karan had dropped a handful of marbles.
