Favourite canon pairing
Let me just start out by saying that I am not a big fan of the Hermione/Ron pairing, nor am I overly fond of the Harry/Ginny pairing in the books. However, I am a fan of Harry/Ginny pairings in fan-fiction, where her character is fleshed out a lot more and she becomes a strong young woman instead of a simpering fan girl. I don’t think that’s my favourite pairing, though.
After a bit of thinking, I’d have to say that my favourite canon pairing is Arthur and Molly Weasley. Completely in love, even after raising seven children together, Arthur and Molly are the perfect couple. Their life philosophies are similar in all the areas that matter, and even their differences complement rather than clash. That isn’t to say they never argue but, even while disagreeing, their deep and abiding love shines through. More, their compassion and kindness are so ingrained that they effortlessly encompass anyone they come across.
Yes, my favourite canon pairing in Harry Potter is definitely Arthur and Molly Weasley.
