It's Still Too Early For Them To Get In My Way

Tiona kept on nudging Thirteen's cheek as her way of letting her Master know that she was upset.

After the teenage boy was done eating breakfast, he immediately went back to his room to check on Tiona's condition.

Having known that it might take him a while to finish his experiment, he had prepared plenty of food and water so that she wouldn't go hungry or thirsty while he was away.

"Don't be mad, Tiona," Thirteen tried to pacify the Black Snake, who was clearly upset because it had been five days since they last saw each other. 

Tiona hissed and pouted. The teenage boy only shook his head helplessly, seeing his Beast Companion on strike.

Since he knew that it would take a while for Tiona to calm down, he went on his rounds and visited his Battalion and the Valkyries, who were training together.
