Fleur and Bill had taken the Portkey to the where the attack was going to happen. She had sent the kids to France so she wasn't worried about them. She was worried about the last time she was in a battle, she was scared that it would happen again.
She would try hard and not let it. If they were going to play dirty she could too and she wasn't going to contain the emotions that would let the Veela out. If she had to, she would change and heaven help the person that did it. "Please be careful, mon amour and do not worry about me I will be fine." She kissed him quickly. She knew it was likely they would be split up during the fighting and she wanted to assure him that she would be fine.
Once the bombs started going off she prepared herself for the battle at hand and hoped she and her husband would come out of it unscathed.
