Vampire's Pet
I asked, making sure that he could be seen in my peripherals.
He seemed confused by my question.
I took that opportunity to further elaborate, less I start staring at him again.
"Well, she obviously lied to Xander that she wasn't feeling well even after she was, and then she lied to both of you about her having a stomach ache."
Still, he looked confused.
"What?" He asked.
I turned my head to meet his gaze.
Not anything else, just his gaze.
"Can't vampires tell if a human is lying?" I asked.
He thought for a moment, finally understanding what I wanted to have answered.
