The biggest question on Arthur's mind was whether Yurirl knew who he was, but it didn't look like it from the way Yurirl acted until now. As the swordsman stood still in front of Arthur, he didn't reveal any emotions that would suggest he knew of Arthur's identity.
In both ways, that didn't change the fact that Arthur needed to lie his way out of this. If Yurirl knew the truth, he would come out as lying and would simply explain his reasons for faking his death.
If he wasn't, then this matter would go to rest. Arthur ruffled his hair and acted confused and frustrated.
"How did you know?"
"I have keen senses." Yurirl didn't reveal his ability, confirming Arthur's doubts that this man didn't know he was Arthur Silvera.
"Do you know of my past?" Arthur asked, probing. Yurirl paused and then nodded with a stoic expression.
"I've read your background. Pardon me for prying, I read all of my dorm's backgrounds to help accommodate them."
