I’ve just seen this on a magazine. On the “red” square says that Charlotte Hope will be Myranda ROYCE, daughter of lord Nestor… So she’s the asoiaf character not one invented by HBO!? According to this magazine she is tge same character as the one in the books… but she doesn’t appear until AFFC, right? And sansa doesn’t go nowhere near her until the second half of the book (that’s season 4). What are they going to do? Couldn’t they let the story how it was supposed to be?
It’s not an officially confirmed role description. I don’t think that magazine knows what they’re talking about- they’re assuming who she is based on the first name and fan speculation. D&D chose not to confirm her casting at SDCC, so she’s probably a very minor role this season. I’d say either a Tyrell cousin compaion for Margaery, or a renamed Roslin Frey.
