It's been some time now that Dra'Meia has been held captive in Equestria and being outside the dream world so long has started to sap her strength as she's also beginning to starve for lack of feeding on fear.

Seeing how weakened the nightmare is Celestia decides to let Twilight try to find out more about Dra'Meia and how, and more importantly why, she had one of the elements of especially considering the elements had been returned to the tree of harmony long ago.

So while Twilight guides the nightmare back to her castle she attempts to give her some friendship lessons and making plans to intergrate Dra'Meia into pony society... It seems Dra'Meia is less than thrilled about this, but she doesn't have the energy to argue at this point.
