Is Evelyn a threat?

(From Demetrius's Perspective)

It was, of course, a lie that Blue had devices around our room that could record who came and went out of our room. I had never heard of such devices. Blue said something like that existed in her world.

Although we had many barriers, it was not possible to make something like that. At least, no one had made it yet. 

Evelyn's face darkened. It was the same look Father used to give when he was angry. Maybe I looked the same as well. 

"Blue, you are crossing the limit here. I do not like or deserve to be accused of something I never did in the first place," she said. 

Blue just stared at her coldly. I had never seen her look like that. It was interesting, but also kind of scary. So, this was how she was when she was extremely angry. No yelling, or throwing things. Just getting cold.
