Sean raises a finger to his chin and taps it thoughtfully as he thought about Hayley's question. As he thought, his pace slowed until he was walking next to Isaac, who had his arm around Hayley. Eventually, he holds out his hand. A tendril of darkness springs from his shadow and collects above his hand, becoming a pitch-black sphere of darkness, as he says, "If I had to guess, it's like your other self says: it's somehow connected to umbrakinesis, or the ability to control shadows and darkness. It's probably a more primordial version of what I can do, though, from the way it feels to me." As the sphere returns to his shadow, he adds, "And you don't just have it out of nowhere. This kind of thing is passed through the generations. A line of your ancestors had to have had it in order for you to have it now."
