Basiclly this is an AU vid.
During the fight after the Yule ball Hermione says a few rash words to Ron that she doesn't actually mean. Ron takes her seriously and, feeling unwanted, leaves Hogwarts. he was planning on returning back in a few days but his plans are inturupted by an encounter with Lord voldemort and some death eaters, which he doesn't survive. An Owl arrives informing Harry and Hermione of Ron's sudden death and both are devestated. Hermione begins to have halucinations and her grades are dropping, she can't concentrate and she can't stop the memories of her and Ron running through her head. Both students and teachers begin to wonder if she is loosing her grip on reality. She can't seem to forgive herself for the words she said to him and she can't help but wonder what it would have been like if she had ever got the chance to to tell him how she felt.
The scene near the begining with the snow and the owlery represents when the owl informing of Ron's death arrives, the scene when Hermione slams down her paper shows how shes frusterated with all the media surrounding Ron's death and how untrue all the articles are, and the scence when Ron pushes past harry and walks off with Seamus is supposed ot be when Ron is leaving.
