Devon was a bit lost but given how Alice bickered with Leo, given how they exchanged words so harshly yet playfully, and the expressions she made all together, he was sure of it.
"So," he spoke up, attracting both their attention. "...Is Leo the owner of the voice that you often talk to in your head?"
Leo snickered.
"Good grief." He said and released his folded arms. "I knew you were smart but you're taking this to another level." He stretched out his hand with a proud grin. He said, "You got that correct. I'm the familiar of this brat but it's nice to make your acquaintance."
Devon, still a bit confused, saw this as a green light and he took out his hand to shake hands with Leo.
"I feel flattered by your remark but... I don't think it was that hard to guess." He said.
"Yeah, since Mark could also guess it." Leo said.
"Wait, Mark guessed it?" Alice asked and Leo sighed.
