The oldest of his siblings, he's basically held the family together since their parents passed. He's the head of the household now, which is a lot of responsibility for someone his age. What most people notice first is how easygoing and fun he is—he's genuinely popular and quick to laugh. But that charm kind of masks what's really going on underneath. He carries a lot of weight, though he rarely lets it show. Physically, he's also the strongest of the brothers, which probably matters more than it sounds given everything he's had to handle.
