Sean grinned when he saw his other sister come in through the door. He watched as Felicia helped herself to the pizza even as he grabbed a slice of pepperoni himself. It did feel good to be among his siblings again, and he sent both girls a proud grin when he saw them like this.
However, that grin ended when Felicia asked that question. Leave it to her to do something like that when they first greeted each other after not seeing each other for some time. He chuckled softly, setting aside his slice of pizza to look casually over at Felicia.
"In my head, huh? You waste no time. Luckily, this guy seems to like that." Sean rolled his eyes. "I've only heard references to this guy before he popped up in my head, as you put it, and that's just because of the kinds of guys you usually find working with computers and the like. His name is Roy Mustang, a General in whatever army he serves. He's told me he's an alchemist, some kind of soldier that's able to create a spark of flames just by snapping his fingers. He seems to want to test to see if I can do it, too."
Sean glanced over at his sister again, lifting a brow as he studied her directly. "I'll ask the question back at you then, sister. Who've you got in your head?"
