The only thing Hermione felt was utter pain. Pain in her pounding head, her heart, and the very marrow of her bones.
One thing kept coursing through her brain: Gone. Ron was gone. And I probably won't ever see him again.
She grasped onto the memory of his red hair...his adorable freckles..his long nose. She held onto it tightly, as if she would forget. She would never forget. She had liked liked him since the first moment she saw him on the Hogwarts Express seven years prior. He had been her best friend, and though they had constantly rowed, she couldn't help the tingling sensation every time he touched her, or even looked at her, for that matter.
Soon, the feeling of 'cuteness' she saw in him went away, and was replaced with something much more. She loved him, and she thought the same was for him. They covered up their fondness with constant bickering. When in truth, they were just scared to say what was really on their minds.
She remembered how heartbroken she had been in their sixth year when he went around snogging Lavender Brown. That was nothing compared to this. He just simply left. Gone.
Gone when she (and Harry) needed him most.
Hermione ripped the locket from her neck and threw it at Harry, thinking the absence of the cursed object would make her feel better.
It didn't.
