Deston's face took on the mask he had learned while in the role of a business man during his time in Ireland. He was tasked with retrieving documents about a business the Church was soon to be affiliated with in some manner. He never did learn in what way. He quickly learned that to get anywhere fast in the business world one needed to put his target on the defensive, a job made much easier by something as simple as a look. Firstly your face had to reveal no lack of confidence less you be eaten apart by questions and be immediately put on the defensive yourself. Next you needed just the right mixture of curiousness, annoyance, and disbelief. Seem too curious and your opponent would take you as gullible and brush you aside. Too little curiosity and they question whether your paying attention and once again they are on the offensive. Too annoyed and they would give up, not annoyed enough and it becomes clear that you aren't a big enough fish for them to waste their time. Same with the disbelief. It was a mask Deston now naturally assumed whenever he felt a business proposition coming. Deston finished the look by crossing his arms and leaned slightly back on his heels letting his shoulders and chest naturally rise. A look clearly out of the other place among the other homeless he had been about to join. 

Deston listened intently to Felix's monologue making sure to contentiously read his face for the tell tale signs of a lie that nearly all untrained in the art give off. He found Felix oddly trustworthy. A trait he didn't come across often in his past ten years of service to the Church. It was either that or Felix was every bit as good and possibly better than Deston at the great game because there was no way someone could spout off such ridiculous nonsense for so long without making a mistake less they truly believed what it was they were saying. Even so Deston couldn't stop his mask from cracking as a slight quip of his right lip twisted into a smirk. "Do you ever listen to how cheesy you come off? 'Will you come with me and help save the world?'" He let out a brief chuckle before continuing. 

"Let's see, you're either a mad man," Deston spun on the ball of his heel turning round putting his hands on his head and walked a few paces away from Felix. "Or you're actually on the trail of some great conspiracy involving the Church. A third possibility exists with you being the greatest liar there is, but that's not possible because there's no one alive in the game that would use that last line. You must be the pinnacle of everything our great church preaches. No wonder you were an Arch-Magi." Deston spun once again on his heel to face Felix. "Anyways I'm getting side tracked with my thoughts. Lucky for you I'm currently in the business of conspiracies involving the Church and my own little investigation has gone cold for now. So why not?" He gave a nonchalant shrug and tilted his head."I'll go ahead and help you save the world." He couldn't help but say the line with grin splitting his face, before his eyes narrowed on the parchment in Felix's hand. "And I'd love to get to the bottom of that little magic vision that told you my name and where to find me. Can't have the happening in my line of work."
