Somehow, Dobby had Harry and Ron in the parlor of Malfoy Manor, instead of the dungeons. They could grab Griphook, but failed reaching Hermione in time. Her leg must have gotten shattered under the chandelier. She knew she could not call for Dobby or even Kreacher, since neither were devoted to serving her, even if Harry pleaded, because he was not here. They could congregate the entire Order, but not a single person could get through the wards, because they were not in the blood wards.
