Mark is a fun gambler, always willing to take a risk. Heir to the Lues family's casino, he exhibits a childish and smug personality not befitting of both age and role. Often times he also sticks in crowds not suited for him, often easily swayed and naive due to his need of companionship—doing about anything just for a sliver of affection. Some say he's a tad bit desperate when it comes to friendship. He's horrible in social settings on a deeper level, he can understand people but he has a hard time acting on it in a way that brings comfort—often throwing money at his problems in hopes of solving it just like his parents. He was heavily sheltered which lead to his give-and-take persona. If he cannot bring results to the table, he is no one—and all he wants is a friend that would make him their first choice.
