Zhe Chouhen watched the door open slowly for him.
"He's here." Wilhelm said, eyeing him suspiciously. "Who's looking for him?"
"A friend from Transylvania." 'Dracula' said with a small smile. "May I come in?"
Wilhelm looked unsettled while staring at him, and took a while before he called out. "Johnny, someone from Transylvania is looking for you!"
"Oh! Mr. Redd--- Ow!" He heard Jonathan exclaimed and then hit his head on something, possibly a shelf.
He waited patiently as the two boys scrambled at his arrival, and focused on how Wilhelm acted instead.
As a vampire, he have enhanced senses. He can tell how fast someone's heart is beating, how much blood flows in their veins..... And this allows him to have a bit of a mind-reading ability. Though it's more like an empathic link that allows him to guess someone's thoughts from emotions.
