Eiro kept looking at the horizon, his mind going crazy to figure out the 'truth' of the situation. So far, this Orc was the oldest one that he had seen here in the village. It was kind of weird that this Orc knew Common so well, despite the fact that he was told by the child that he was the only one that knew Common.
Since that child was telling the truth then, this meant that it didn't know about this Orc's ability to speak Common. This elderly monster was hiding this from those around it, but felt free to simply show it to Eiro without a moment's hesitation just because of who, or rather what, he was.
Such things and much, much more ran through Eiro's mind before he came to a conclusion, "So it really is you that is killing the other Orcs."
