Catching Ashelia's widened gaze easily, Sephiroth remains at his cold-neutral base of expression. Seemingly neither surprised or disappointed that she hadn't noticed that he'd been tagging along from the floor above. He's made it a careful habit of his, so far during his tenure here, not to draw too much attention to himself; it was the smart thing to do while he was still finding his feet.

Given what had been explained to him already by Takeshi, he was getting used to the idea that many people might know his name on sight, even if they didn't know him. To be fair, he'd rested on the conclusion that it could only put him at an advantage. Besides, the less introductions he had to give, the better.

He let Ashelia's question go unanswered, after all, it wasn't the time for idle chit-chat. Sephiroth tore his gaze away from her and looked over Dylas, then Frisk, and then back to Dylas.

"It would be ideal to be prepared-" He gestured with open arms towards the very emptiness of the room. "-though unless you've any skill in sensing traps, it would indeed be a waste of time."

Indeed, he wouldn't move to stop Dylas at all, from pulling the lever if he had the intent to. Yet Sephiroth hasn't moved even a single footstep more forwards towards it; he has a wide enough field of view from further back.
