Age

Suddenly the air in the room felt colder. Theia takes a step back, intimidated by the doctor presence. However, she stops once she realizes that he couldn't really hurt her.

"I would like to know"

She mustered up her courage a bit. Hilda's condition isn't so great, the maid felt rather restless about this whole thing. She wanted to kill this guy but no matter how hard she tried, the doctor just won't die.

Perhaps it would help if she learned something from his past. The doctor took another sip of the warm water, using it to stave off the chill of the winter air. He opened his mouth, releasing a puff of steam that mingled with the cold around him.

"Could You guess my age?"

Theia squeezes her eyes and uses her brain a bit. From what she heard the incident happened 20 years ago, which makes his age a minimum of 20. Then she needs to account for the fact that he massacred the whole village which a kid could not do.

"forty?"
