just a thought as I was doing the review of the episode. I read about Ramcharitmans in detail and as Kirthi said it ends at happier note. So the giving of Ramcharitmanas by dadi could mean that the makers are also taking the happier route and not looking at seperation interms of shivika.
Another point to validate that this all a plan in the bookduring Aranya Kaand it mentions, " Rama knows that Ravana's intentions and orders Sita to place her shadow (Maya Sita) in her place, while she would hide in the fire.( a disguise is due in plan) She asks Rama time and time again to hunt for the deer and bring it to her"( anika constantly trying t tell shivaay about something)
We have discussed this possibilty on twiiter as well.
So lets really see how it plays out
