ah, beat me to loading it from the article.

Oh I don't think it's that big of a problem: they've spoken of the Water Gardens already in Season 4, apparently distinct from Sunspear. Maybe they'll speak of them as sort of like a suburb of the Sunspear complex to avoid confusion -- but I mean it's an extension of Sunspear of a sort; it's just a couple miles down the road (to be exact, "three leagues", or about 9 miles (14 and a half kilometers?) -- I mean I think of it how "Flea Bottom' and "the Red Keep" are both part of the overall "King's Landing" location.
