Cal noticed the Darkness demon just lurking around. So he figured to send the thing a message. He whispered to Bart in some dark sounding language. The imp nodded and vanished from sight. Cal turned to Ariana. "So you from around here? I'm from the Deep South but I've figured how to hide my accent. With magic." He said like it was something obvious. "Not easy to sound menacing when you sound like you are speaking through a mouthful of honey. " He said shrugging. 

Bart would appear right in front of the demon from before. "Hello! Master says I should talk to you. To tell you he was sorry for hurting you before. He also requests your name. Your mortal name. I'm Bart. " The imp said feeling bold by the fact that he was protected from harm.
