"Come on, Harry!" Bill urged as Hermione laid her hand on Dobby’s back. House elf magic didn’t operate by the same rules as human magic, and apparently one benefit was that Dobby could apparate past the Malfoy’s wards, taking humans out too using side-along apparition. Her eyes met Ron’s as they all jostled together and she saw horror and empathy written over Ron’s face as his gaze cast over her. It was awkward, too intimate, and Hermione dropped her eyes and her cruciatus curse sputtered to a halt. Just as Harry reached Dobby, Bella scrambled to a crouch and pulled something glinting silver from her clothing. A laugh erupted from her twisted mouth as she threw the silver blade toward them.
