They enjoyed these moments, and Berry was the one who knew what William wanted to do. It reminded her of what he did back at her clan, and recalled how he pushed her over the stage to enjoy the warm welcome of her clansmen.
William did want them to enjoy the glory they worked hard for, and yet this wasn't mainly why he gave them one more week. Karoline was still sleeping, unconscious, and didn't show any sign of waking up even after all this time.
He stopped training and started to add more spirit power gathering arrays, even using lots of spirit power affiliated materials to aid in speeding up her wake up.
Then he returned to train for one more week, hoping by this time Karoline would wake up.
"What happened to me?!"
Just after he did all this for her, and as he was in the middle of his training, Karoline finally woke up. And yet she wasn't feeling the same as she was before.
