I accept lots of different interpretations of canon as long as they make sense within the framework they themselves impose, but I just love discovering these little details. Yay details! It's like the opening sentence of the epilogue, 'the air was crisp as an apple' or something like that - for me, thinking this is a signal that canon Harry might be consuming untradeable magical substances. He gets these visions with the pretty sparkling mist and sees other characters' eye colour despite the mist and distance... Looks like he's magically high:) (I think grey_hunter even wrote a story featuring a similar bunny.)
