One of my favourite things about Harry Potter is that Harry is such an unreliable narrator, not because he’s lying, but because he was so oblivious, just about anything could be going on under his nose and he wouldn’t even notice. It’s great because it supports basically every headcanon. Like, no, Harry would not have noticed if Sirius and Remus were dating, I know he’s The Chosen One but he’s about as perspective as a pile of bricks.
