Green light plays off the curved walls in fitful sparks and snaps of electrical charge, Tony almost negligently holding up his hand to see by it. He goes carefully, each step considered and tested, but not slow by any means. Ready to hit the brakes if someone awful happens, or hit something awful with blasting Fade energy.

He wrinkles his nose at the smell of this place. "If we need to get all Crawling In My Skin on another weird blood lock, we should probably wipe it down first," is his suggestion, which barely echoes back to them in the oppressive silence.

No pausing to say so, though. Now and then, the fact he can't hear their footsteps compels him to glance backwards more often than he normally might, but otherwise, onwards.
