Fleur's greeting was so effusive that it caught Charlie completely off-guard. "What else could a brother worth anything have done?"
He tried to sound more disarming than amused by her predicament, but somewhere along 'brother' he became aware that he had begun to mumble a little. He shook his head, feeling suddenly very thick. A frown threatened to tug at his mouth, but any concern was suddenly subsumed with a general feeling of lightness and well being. He chuckled at Fleur's admitted inebriated state, heat warming his cheeks for some reason he couldn't quite place.
He looked over at her when she began pleading with him, and suddenly he felt as though his entire life's work had lead him to this particular moment. He took her hands and held them between each other, gazing into Fleur's face. "I solemnly swear, upon even my miserable life, that I will never utter a word of this to anyone, not even you. You have my word and vow." He let one of her hands go and thumbed her chin a bit, giving her a grin. "Let's get you home to my dear brother. It's a wonder he hasn't gone half-spare."
