They will show mastery of their acting skills and understanding of their characters which in turn will lead to Romione perfection in DH. For them personally, nothing will happen. They have stated time and time again that their friendship is like brother/sister. Rupert plans to continue acting while Emma is currently attending Brown University in the US. She currently has no plans to continue acting other than her non-HP project, Napoleon and Betsy. For the last two films though, I feel that they will play this couple brilliantly and possibly even expand on them too. Supposedly, there is a scene between the two of them in the Chamber of Secrets that wasn't in the book. A finding of concept art for this scene was reported by a fan who visited Leavesden Studios over the summer.
