Jacob is a natural-born leader with a heart of gold and will do anything to protect his people -- people being the crew of the ship Inevitable. He's kind and optimistic, but only to a fault. He might verge on cynical, on occasion. He's brave and courageous, and is willing to put himself in dangerous situations if the reward is high enough. Although appearance-wise he's a pretty big man, he has a softer side to him that he's not afraid to show. He's intelligent, able to think on his feet.
