The souls in his head screamed for her blood. He commanded more respect. Nico didn't know, but that voice was Minos. Who wanted revenge. Minos had been… well pissed to say the least after he was dethroned as ghost king. So what did he do? Warp Nico's mind and set him off when Will tried to do his job. Duh.
Out of the corner of his eye, Will saw Lana back away. He watched Nico's eyes darken, watched the shadows swirl more rapidly, and yelled for everyone to get out. Nico's eyes narrowed, and bones erupted from the ground. Not even bothering with entire bodies, the bones whacked at the people trying to get out, making it take so much longer than necessary.
"What. Is my control not enough? Well maybe someone can teach me. Oh wait. No they actually can't." Will internally scolded himself. He should have thought about it.
"Nico, please hear me out. I'm sorry. It's been a long day, and I didn't think about what I was saying." One of the bones knocked the back of his knee, and Will fell forward. He saw Nico's eyes flash with regret, and then watched them darken and become almost emotionless. Will's eyes narrowed. Well it definitely wasn't Nico. It was…. But not? There were no golden eyes, so it wasn't the Eidolon things. Thank the gods. That would raise the question of how it got into camp-
The shadows swirled around Will, more bones scratching him, and he snapped back into the present. Haha. Right.
Nico was most likely possessed. That much was quite obvious. Will had no idea where to go from there. (A/N I have no idea where to go from here either, isn't that fun?)
