Mathius Collet's Links
Mathius tends to bother Lazaro when he's not hanging around Kodiak. They're not exactly friends, but Lazaro is the only guy who won't start a fight to get him away.
Lazaro tolerates the guy. He's the closest thing to a friend that he has, but even saying that is a stretch. He can't say that he's a fan of Mathius.
Mathius idolizes Kodiak to the point where it's a little obsessive. He had become the boss's unofficial assistant, kissing up and doing whatever he's told, no questions asked. While Mathius wants to be as deadly as Kodiak is someday and admires his work, he feels the need to challenge and kill him one day.
Kodiak finds value in the young, eager assassin. While showing concern over Mathius during his episodes, being emotional or violent ones, it's really hard to say how Kodiak really sees his unofficial assistant.
