"See, that just raises more questions than it answers."

"It's possible we can replicate it, if you had anyone in mind."

"I don't know anyone who's died here."

"It's possible it will work in your world, if summoning works here."

"Is it actually magic? I thought these Dread Doctors had synthesized the blood somehow. I don't suppose they kept good notes..."

"We don't have a good way to get the blood back to our Earth. No one in the daeva worlds can die."

"Could someone from your Earth summon you with it?"

"If the binding permits it."

"Or a demon could make it, if it's not magical."

"Do you know any friendly demons?"

"Summoners don't usually offer to let them socialize the way angels and fairies do."

"Alright. I suppose the next step is to use our magic to get to your Earth."

"That didn't come up as something you might be able to do."

"It isn't, yet. I'm optimistic, now that I know what I know about your summoning. If the Nemeton is actively engaging with the world, and with a hellhound in town, we have more leverage."

"I see."

"If you think we shouldn't focus on it, he won't."

"It would certainly be... interesting, if it could be done."

There's a knock. 

Dr. Deaton goes to let in their guests.

"You must be the new daeva. I'm Scott McCall. This is Stiles."

"So what can you do?"

"I'm an angel." He flutters his wings demonstratively. "I change things into other things."

"That's nice. But really, what?"

"Could someone do this by accident?"

"It's harder for me to demonstrate than Ellie; I need some raw material to work with."

"Possible, but unlikely. It requires a specific phrasing."
