OOTP conference yields clue to Book 7

At Saturday's OOTP press conference in London, producer David Heyman was asked which character was referred to when they were advised by JKR not to cut it from the movie. Heyman responded with this:

“Jo reads each draft. She reads each screenplay, and she said, 'You know, I wouldn't do that if I were you. Or you can, but if you get to make a seventh film, you'll be tied in knots.'”

“Which character was it?” he was asked, but Heyman teased, “I thought you might ask that. I'm not going to say.”

Luckily, however, MTV News caught up with director David Yates yesterday where he submitted. Please hightlight below to see what he said because it contains Book 7 spoilers:

—>“It was Kreacher, actually. We took Kreacher out, and Jo said, ‘Listen guys, you don’t have to put Kreacher back, but I’m just telling you, if you want to kind of keep a thread going for six and seven, you might want Kreacher to come back.’ She basically told us Kreacher plays a role in Seven, in a sense. She hinted. We thought about it for five seconds, and he came back.”<--- Read more on this here (link contains spoilers).
