About the romance between Ron and Hermione in OotP (2007): "The romance between us is there if you watch carefully, it's all underneath the surface. There are hints of it all the time and at one point Hermione and Ron have a duelling match and she absolutely smashes him into the back wall with this spell. And Ron is pretending, "Oh yeah, I let her do that, it's manners isn't it?" which is quite funny."
