The level of power coming from Noctis isn't the most worrying part of the whole situation. Noctis looks to be getting closer and closer to an enraged state. The moment he reaches it he'll be blinded by it. He doesn't know him well enough to snap him out of it.

Shiro transforms the bayard into a shield. It holds up to demonic assault a s the world fades out and fades back in. He lowers his weapon. Silver blue light washes over it shaping it into a sword over his right arm. He comes up to Noctis right side and touches his arm. "Easy. This is a memory and we need to talk to him to discern why you can't wake up."

He stares at the man unable to shake how he'd looked when blackness had oozed down his face. Shiro breathes in. "This world shaped from memory...What do you really represent in it? You're not in the next part. Yet you're conscious."
