"Livingstone, do you happen to know who has taken care of the attackers?" Valnaro asked. From his point of view, since Livingstone and his team were here, they had to have some relationship with the hotel.
So, perhaps they knew who had taken care of the 14 people who had attacked today.
Livingstone and the others were puzzled when they heard this. They had thought that since the army was here, perhaps they were the ones that had taken care of the situation. But from the looks of it, they were completely wrong about it.
Now, they were wondering who it was that had taken care of the attackers. It was obvious that the person wasn't ordinary. But, no matter how they thought about it, they didn't think that they were familiar with anyone of that caliber.
