He rummages through his pockets.

One paperclip, a pen, and a handful small denomination coins.

Now it's one paperclip, a pen, and a handful of other paperclips.

"Conservation of mass? How much do you have to know about the stuff you're changing, or what you're turning it into? Can you change me into something?"

"Yes, a little bit more than nothing or more for complicated things, and yes but I won't."

"Thanks. Deaton told us you were curious about the Nemeton?"

"We think it is what summoned me here."

"We suspect the Nemeton may have drawn her here somehow. As far as I know, nothing like summoning has existed in our world- but now it does."

"You think it wants blood again? I would totally offer but I'm still using mine."

"I can make blood. If we turn out to need it."

"Good to know."

"The Nemeton gets its power from being a ritual place for druids for a long time. Sacrifice is kind of a theme, because all the really strong druidic stuff is based on sacrifice. That's how me and Stiles are connected to it, we did a ritual sacrifice."

"What kind of sacrifice?"

"It was pretty easy as those go, I guess? We had to drown ourselves in ice water, and we all made it back okay."

"Good ol' cardio-pulmonary resuscitation."

"Emotional tethers," he disagrees.

"We each had someone there who meant a lot to us, as...incentive to come back."

He looks at Ellie, who shrugs.

"Magic, then. Close enough."

"Actually, if you two are close enough, you could try it. It might be enlightening; the Nemeton put all this work into bringing you here, after all."

"It's somewhat hard to kill a daeva."

"Even a black hole is at most an inconvenience."

"Is that a deal anyone else can get in on?"

"Not easily."

"Should we try to find it? Lydia and Parrish might be able to help, too."

"We've already called the deputy."

"Isn't it a tree? Does it move?"
