Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"Hello. Well, it looks like summoning works more-or-less as normal in this universe."
"Seems like it. Which is good to know if, say, Professor Xavier wants to get out of his wheelchair, or if any locations need to be deradiated, or if you want to run an electrical generator on books and candy and interesting shoes."
"I don't think either of us are going to claim the third option appeals. But--the first one, that."
"Cool. I can recommend you a medical angel and do most of the circle for you so you don't have to worry about getting a binding wrong, even."
"Well, I should actually ask him first. I strongly predict the answer will be yes but that doesn't make it okay to make arrangements for his medical care without consulting him."
"I cannot bring a medical angel to this world without assistance. Daeva cannot perform summons."
There is a pause, as she presumably asks.
"He wants to know more about the procedure."
"I'm not an angel. But at a guess she'll ask what the nature of the problem is, if it's particularly complicated she'll anesthetize him and open him up to have a look at it, and then she'll change whatever he's got into functional whatever-isn't-functioning. Won't even leave a scar."
"Probably take a decent medical angel five, ten minutes. Longer if he wants her to fix atrophied muscles below the waist."
She worries at her lower lip a little, sounding like she's listening to something no one else can hear. "Okay. He says go for it. So: all but last bit of a properly-bound angel summoning circle?"
Cam hands her a rolled-up piece of paper. "You must also be careful about task negotiation. If you are the least bit unsure about that I can do it for you and you can just say 'yes' when I cue you. I mostly trust this angel, but mostly is not absolutely and angels are only a little less scary than demons."
"It can be. Again, I mostly trust this angel, but I don't want you picking up bad habits - I mean, apart from summoning me personally unbound, but you already knew that was safe."
"I mean, how in particular is it tricky, do I not just tell them what I want them to do and ask them what they want for it?"
"You do that, but if you are imprecise, then there will be loopholes. I can teach you summoning properly if you like, but if you don't want four college credits of it before the professor gets to walk, let me do this one."
Um--I don't know if anyone mentioned this to you, but Professor X is Emily's dad."
She lays the sheet of paper down on the floor and fills in the last bit.
An angel, pale, white-haired and white-feathered, ornamented with tiny little jewels embedded in her skin starting at the fingernails and thinning up to loose spirals at the shoulders, in a floorlength sleeveless dress, appears. She inclines her head politely, seems to almost recognize Cam. "How may I help you?"
"The summoner," says Cam, "has a person of her acquaintance who was shot in the spine - slugthrower - some years ago and cannot walk. What might you want for a complete repair of this injury?"
"...You seem familiar."
"We've met, but it was a long time ago. I'm a demon, obviously, and can provide your payment within the obvious constraints."
"Very well. I'll accept a Inkralir model computer and its chip, inserted with no other interference, provided by you, for the work."
"On a default?"
"If something happens to prevent you from providing the summoner's payment I will accept a token of a piece of fruit."
Cam makes an orange and puts it near the circle. "Say you accept," Cam tells Edie.
The angel picks up the orange and steps out of the circle. "Where is my patient?"
Apparently, the school has a decently-kitted (for the late twentieth century, anyway) infirmary. The Professor is waiting for them there.
"I'll help," Cam confirms. "I have my certs."
