The vulnerable Anuj and Mukku are indicators that the wounded child in them has not found closure to their loss. Both are deeply traumatized have applied a band aid and assume they are okay. Like the shahs the brother sister have not vented their pain.
It was Anujs 25th birthday but an adult like him too has instead of trying to heal has endured his guilt and deep pain.
Mukku has other health issues too it appears. One way by which the Shahs can redeem themselves if they can help anuj and mukku heal with their love and care. Anupama will do her bit in the process though.there is a big dhamaka that must have happened that took mukku away for a decade. She must have had her share of the property with which her investments and travel were funded.
Anuj has been an unconditional giver of love and care to Anupama. Now it is her turn to be a catalyst in the healing of the Kapadias.
Kavyas insecurities will keep surfacing may need attention too.
