I think tolu molu will bring gauri home the family n tell pari miss gopi that she has no parents, it will be when she sings just like gopi slowly gopi will realise. Did meera have a bracelet or charm that was given to her? that gauri may still have.
The episode where gopi drops meera Ahem runs towards the water saying he can hear meera he was not lying he probably could hear meera but radha had done something to her
