Or is she. She doesn't seem to have found her Muggle existence very meaningful. Now that she's presumably going back to the real "first world", her rightful place, to reunite with what's left of her family, I see it as at the very least a possibility that she'll look back at it with contempt, and resentment for whoever removed her from her real life.

Of course that's just speculation, depending on what kind of a person she is - I imagine diferent people in her position would have wildly different reactions to something like this.
