Hermione hadn't been on a field op in months, not since she'd moved in with Ron. It was good to feel the old adrenaline rush wash away the last remnants of exhaustion as the protective spells clicked back into place. "He's not getting away. Not this time," she said between her teeth.
Especially since this time it was Ron who was threatened. You aren't getting him, you bastard. Not a chance.
Her wand was practically glowing as she followed Harry toward Schloss Niederhagen.
