He was in an extremely good mood at the moment, but that good mood flinched for a moment the moment that he heard the news.
Since Gaia belonged to him, and he had already activated his 'sense area' he had been able to create a connection with it and understand what was going inside as well.
The reason why his mood flinched was because he had just learned that Amelia and the other woman had awakened from their slumber.
Seeing the beasts around her pressuring her and unable to move she was in panic and seemed to be trying everything she could to break the pressure.
If it weren't for the presence and the words of the women inside, who knows what she might have done, but it looked like she had stopped being a pain at the moment.
As for the other woman, she was still unable to understand what had happened and why was she still alive, as she started struggling as well.
