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.
"I haven't done the malaria yet. I will need to travel to where malaria is found."
"There's a few reasons I don't usually tell summoners that, but yeah, I used to be a human."
"Well, one reason is they usually summon me bound and gagged and I am literally unable to communicate with them."
"Aforementioned rumor about demons taking people's souls. No one wishes to be cajoled out of theirs. The binding is a legitimate safety precaution when you don't know who you're getting - the gagging is ultimately quite pointless."
"Because some demons think it's really fun to convince summoners to offer up their souls and have gotten very good at it. This is really the safest equilibrium, because the souls are being traded for something, the something is real and the soul is not - or at least the claim on it isn't - and if it were common knowledge that there was nothing on one end of this bargain you'd still have an asshole demon and a desperate summoner and that gets less pleasant fast."
"That part makes sense. I've just never understood how you can be so afraid of someone persuading you to something that you don't let them talk--if you expect them to have arguments you'll find swaying, that should sway you. I don't understand what irrational appeals could be made that wouldn't fit into that category--verbally, anyway. I do understand how the application of...stimuli can impair one's judgment."
"Stimuli. Threats. Insinuations that there are loopholes in the binding. Outright bribery - you summoned me for this thing, but imagine if I also did that thing, which is not in the scope of what you asked and would require additional payment?"
