When do ron and hermione start dating in the books
Those two have liked arguing with each other from the beginning.
The thing I like about Ron and Hermione's relationship throughout the books is just how affected they are when something happens to the other.
Their emotional reactions are always much more intense than Harry's.
From the beginning he's been interested in Hermione. Harry doesn't like Hermione's argumentative nature, whenever she starts her nagging and pushing he tries to get away from her.
But Ron can't seem to help himself, he always has to respond.
Ron gets a pretty nasty detention from Snape in Po A after defending Hermione in class.
