Oof. Even gently, he packs a punch- like Gladio. At least it was only his shoulder. Noctis watches as the crystal comes out, leaning in to get a closer look; it's different from his own Crystal, thankfully, else it might have made him flinch away. He's still too close to those memories, of being pulled inside and given a revelation he wasn't prepared for. This is smaller, softer. It doesn't pull at him the way his own did.

"That's what the secrecy's for." It makes sense. If he'd used up too much of the Crystal's magic, he wouldn't want to risk burning it out. It's similar to how he wears the ring but doesn't use it- great power often requires a sacrifice. "What kind of emergency? What can it do?"

He'd rather not depend on whatever power this can offer Ardbert if he doesn't have to, but it's good to know the conditions attached.
