There were a lot of words in there that Souji didn't really understand - genetics, being the leading one. Still, he listens to Fayt's story, knowing that this was something secret, something that had been kept from him. A large scale threat to their universe that maybe had something to do with that 'realms' thing that Albel had mentioned in his rage last night. His chin unconsciously floated up and off his hand as he listened, all his attention on trying to understand what Fayt was saying.

Before he was born, three kids, different abilities - Souji's eyes widened slightly and he lowered his hand, straightening as the gravity of Fayt's explanation came to bear. His father had experimented on him before he had even been born - Fayt had to be one of the children with this chosen ability to save their universe. He, himself, was a weapon or a weapon wielder who had the task of saving everyone and everything.

How did he even respond to something like that? He saw Fayt in a new light now; one tinged with sympathy. To be so young with such responsibility had to be a terrible weight to carry. "It's no wonder Maria-san and the others were looking for you then. Did she know or was it just a hunch?"
