Ignis clears his throat and pushes his glasses up, noting the distress from both Gladio and Noct at the display. It's unlike anything he's heard of before, if John's description is accurate. Who's ever heard of a Guide weaponizing their abilities? It's intriguing, to be sure, and he makes a few mental notes on what he'd like to go searching for online tonight once everyone turns in. But while the man can appreciate it intellectually, seeing it first-hand is more troubling.

"Perhaps it would be best to see if our resident Sentinels are willing to be tested for you to develop such a skill, Prompto."

John glances over at Noct. He can feel the uncertainty coming off of Gladio, and it's nothing new. The Sentinels in his unit were never entirely comfortable with his abilities being targeted at them in that way, and John hadn't actually used them in that manner too often, just when someone decided they wanted to try anything with the unbonded Guide... or on enemies. He really hadn't the slightest remorse mucking about with them and their own Guides on the battlefield.

The doctor sends out a pulse of reassurance to Gladio across the Bond and continues to pump out soothing pheromones for Gladio's benefit, as well as Noct's. "Ignis has a point there. Happy to walk you through how I do it, but we'll need a volunteer for you to really get much practice on it."
