Kaius was badly injured before he was let go. It took a few hours before he could recover but he searched around, trying to find her to no avail.
He tried everything possible, using her scent and he couldn't.
It felt odd, he knew she couldn't stay in the pack and have her scent so greatly concealed, he concluded that she must've returned to the human world and he went to the human world.
He went to the house first, trying to see if he could find her, he found Anna on his way inside and she stopped him.
She asked about their emergency and if Brielle was fine, he didn't quite understand her words for some moments but he nodded hastily, coming up with an excuse about how he needed to get some things at home before returning.
After basing Anna farewell, he entered the house, searching around for her and to his horror, she was nowhere to be found.
Everything was untouched, she hadn't been to the house and it terrified him greatly.
