He's a businessman and one of the few remaining patrons of Lackadaisy. Wick is elegant and well-mannered. He tends to appear as a mature man, even if he embodies some eccentric characteristics: such as his passion for rocks and collecting in general. Other businessmen like Edmund Church are not very close to Wick and treat him with distrust. Though he is proud of his vast collection of objects nonetheless, and is willing to present them to other people to earn their friendship. 

He has a cheery, guileless manner of speaking, and when talking about rocks, geeky enthusiasm shines through. There's a bit of well-to-do Bostonian in his voice. His accent might sound something like Cary Grant impersonating a Kennedy...but understated.
