Here's the demon, studying his copy of the blueprints as he walks slowly behind Sikandros. He's gagged, of course. He coughs, sort of politely, when smoke wafts into his face.

Sikandros WILL NOT COMPROMISE on the smoke. He likes smoke. It's very thematically appropriate for him.

He can, however, provide it in a wide variety of colors and scents, and thin it into a mist so it's less cough-producing.

Cough cough! Waving of smoke away from face with one wing! A quizzical look when the scents cycle around to "vanilla"!

Sure, why not, vanilla smoke.

"I invite you to provide any preferences your binding will permit, demon." How about dry ice? He's personally rather a fan of the steam effects you can produce that way.

Dry ice still gets wafted but not coughed at.

Right, but, see, they get to stride down the middle of a corridor that wasn't there yesterday through a rapidly expanding column of smoke, vaporizing matter as they go. How is this not inherently cool?

The demon cannot comment! He can just lay track and pause occasionally to add various other features like lights and sprinklers and such to the tunnel.

Colored dry ice! Scents! Dramatic tramping! He doesn't literally have a theme song that plays (that's not in the angel powerset) but he's clearly one of these people with an aura of Having A Theme Song.

Any nonverbal comments the demon wants to be delivered can be delivered; if not, Sandy doesn't have much to say to someone who can't talk back.

He may first notice the demon - tripping and falling down gracelessly behind him, getting up, dusting himself off, and collecting his blueprints back off the ground.

The demon doesn't start walking again after that.

Sandy moves to offer the demon a hand up instinctively, but when he rises before Sandy gets there, his response is to give a polite nod and get back to work.

Then the demon doesn't get back to work, he gives a glance over his shoulder - and there he is, not moving.

"Is there a problem?" His voice is smooth and arrogant enough to disguise the genuine question.

The demon shoots him an irritated glance, is unable to nod, but waves the blueprints in the air.

Sandy will superspeed over! (It's so rare he gets to use superspeed for something; mostly it's just used to discomfit people) then, assuming the demon will let him have them, snatch them out of the demon's hand.

All right, what are the... problems... with...

UGH.

"Yes, I see the difficulty."

Right?! Angry tail lash.

"Structurally unsound, and obviously so. The first time there's an earthquake under this tunnel, Limbo will have new inhabitants."

The demon kicks a wall irritably.

"I have no doubt you would have your own choice epithets if your gag was loosened," he says. Pause. "I can provide the requisite forum posts, if all we need is a denouncement, but the word of Duke Sikandros has little sway among the engineers of Earth - and so the question then becomes if we have a way to have the work done well."

Cam blinks at "Duke" and then points at him, makes a "talking" gesture with his hand, and aims his thumb over his shoulder back the way they came.

"Yes, yes, if mere words will serve I have them and to spare." He raises an iron eyebrow. "You have my sympathies. No, if they are prepared to take instruction from an angel and a demon, we can so instruct them, and no harm will be done. The difficulty is that if our summoner desires to dismiss us, we will find ourselves in Hell and Heaven respectively, they will summon substitutes to finish the work, and we will have failed. So we should go - but go as ready as we can, for if our first choice of plan fails."

?

"... Frankly, other than 'blacken their names to the world if they dismiss us without mending the errors', I have few recommendations. Much of my time is spent attending to my own domain, and little enough here on this earth."

Tailswish. Shrug. Turn to go back the way they came.

"No secret schemes? Alas."

And he'll follow. He's ready to invoke his True Name, to engage in blackmail, and to just honestly explain the problems. Hopefully one of these will work.
