rough translation of Emma's french interview to English.

Hermione changed much. At the beginning, it was very first of the class, very with … But it evolves/moves, it grows. Its friendship with Harry and Ron s' is reinforced, its feelings for Ron are also reinforced. It takes care of Harry enormously also, like a kind of mother or big sister.
Many people wonder why it does not finish with Harry but c' is rather logical: c' is a friend and a mom for him, and in this sixth film one sees really their friendship growing. C' is really sympathetic to see and play… (...) Since the departure I knew that Ron and Hermione would finish together! I knew it! (Laughter) Hermione starts to accept its feelings for Ron, this qu' she refused to see up to that point. Ron does not suspect nothing, even if unconsciously, it feels the same thing qu' she I thinks. They are sought, they are … C' is thus an interesting evolution of their relation which is approached in this sixth film.
And c' is pleasant, whereas the saga becomes increasingly dark, to preserve this light key through these two characters. I think that J.K. Rowling managed to find and capture what c' is that d' to be one or a teenager. All these strange situations where one learns the plays from l' love… C' qu' is something; it includes/understands very well. When j' read the seventh novel, and the scene of the kiss between Ron and Hermione, j' stays divided. D' a side, j' stays charmed for Hermione. And of l' other, j' stays panicked! It will be necessary that j' kiss a seven year old friend… (Laughter)
