Believe it or not, he's Stefy's twin. He's same age, but smaller, shier and lacks of self-confidence. He's a follower, not a leader; a listener, not a talker. He defuses conflict and is much more interested in being part of the group than a good detective. However he is always prepared for any situation: he has developed a wide range of practical skills, like being the gizmo-maker or imitating all sort of voices. Thanks to Stefy, he is slowly coming out of himself. Oh, his real name is Oscar.
