"I find I'm not questioning why the Joker decided to bring a shirtless, barefoot fashion model into this so much as where he found one. Hi," he says. "John Blake. Please call me John."

"I'm not a fashion model - although I am flattered - I'm a demon, and he summoned me, by some combination of dumb luck and freak accident," says Cam. Then, realizing belatedly that it's 2012 and he's still wearing his new leather coat, he shrugs the coat off and unfurls his wings a little.

"He's a nice demon," the Joker contributes. "Don't worry."

"What a solid recommendation. I'm convinced."

"I am a nice demon. He summoned me really ineptly and I can do whatever the hell I want - so to speak. I am sitting peacefully on this couch, eating a churro. Do you want a churro?"

"Sure. Why not."

Cam makes him a churro.

"I'm re-reading my old physics notes to find what you might want your nuke wrapped up in, since it may be that I do not have time to put it in a small spaceship and haul it into space. I already made you a - call it a Geiger counter. It picked up some things." He tosses the Geiger counter to John. He resumes re-reading his physics notes with one hand while he handles his churro with the other.

John examines the Geiger counter, more to investigate its general sci-fi look than for anything it can tell him; he doesn't expect to be able to operate the thing without at least a short explanation.

"The major question is how to get close to it once we know where it is - since I bet there's somebody by it, possibly somebody with an 'on' button. Also, it is looking rather difficult to contain nuclear explosions even with 2159 tech. You really would be better off with an angel for this job, although they'd still have to get close to the thing. It's possible you should just summon an angel, I can teach you how."

"Okay," says John. "How do we summon an angel?"

Cam finishes his churro and conjures a clipboard with a piece of paper clipped to it, and a pencil. "I'm not positive it'll work. I don't know why I'm here. Maybe whatever glitch let me land in the wrong universe doesn't apply to angels, or to anybody but the first summon, or something, I couldn't possibly tell you. But if it works like it should -" He sketches a angel-summoning circle. "You draw this on the floor, any medium works, I've seen everything from blood to suntan lotion to watercolor, and then you get an angel. Since this circle is not incompetent, the angel stays put in the circle until you have agreed on a task for the angel to do and what the angel gets out of it. Then they can leave exclusively to complete the task and collect their payment. You can get rid of the angel by concentrating on meaning to do that for a minute or so at any time before they finish their task or after they've got what they agreed to take as payment, but not when they've held up their end of the bargain and you haven't. Some people like to pay in advance for that reason. Daeva of any kind can't go home on our own recognizance once summoned unless we kill our summoners but angels are sort of culturally unlikely to do that. Not that that's a guarantee. If you can't agree on anything with the first randomly chosen angel you get, you dismiss them by concentrating on meaning to do that for a minute or so and you have to draw a new circle, old one's used up. I'd recommend a specific angel but I don't know any who are noticeably better than average and all my knowing's way out of date anyway."

"I have markers," chirps the Joker.

"Sure. Okay. Let's summon an angel. Does it matter which one of us draws it, besides who has to do all the - concentrating?"

"I can't do it, but unless the glitch that brought me here is something about this guy in particular either of you could do it."

The Joker tosses a black permanent marker to John.

He catches it easily. "I'm not even going to ask if I can draw on your floor with this," he says, "because, God help me, I know you. Can I see that clipboard?"

Cam hands it over.

John carefully copies the angel circle onto the floor by the front door.

"Whoa! An angel!" says Cam, rolling his eyes.

"I'm gonna go out on a limb and say you were expecting me ahead of time," she retorts.

"I told them how to summon you. They know exactly nothing. I'm off-leash and also here for some reason it is the year 2012 and there is a nuke in this city I've never heard of and I was like 'an angel would suit your needs better, gentlemen'."
