Aiden turns his focus towards the Grim as they walk through the tunnel. He really never seen Grim up close and this was sort of frightening for him. Actual monsters right before his eyes. Though before he could make a comment about them, the group stop. Aiden saw Silvi picking something up as he walks over to her. 

"Huh, someone must have been down here already." Aiden looks around as something came to his mind. Not saying anything yet to his teammates as he didn't want to appear paranoid. His eyes shift around to see more of the cave. If glasses were on the ground and damage. That could mean he was attacked by something. Though there no blood so it wasn't Grim. He didn't have a good feeling about this.
