Douglas nodded very seriously at this. "Your praise is entirely accurate. So, now that you've finished stating your demands, isn't it my turn to make some?"
Aragog looked at Douglas in confusion. "Didn't we already agree? My children will supply you with silk and other materials. What else do you want?"
He finally noticed something wrong with the atmosphere. Hagrid was fidgeting, Douglas wore a half-smile, and Newt's stare made his skin crawl.
He instinctively tried to move into the cave, but his legs would not cooperate.
In the end, Newt spoke. "I need you to do me a favor."
Aragog looked at Newt and breathed a sigh of relief. "I know you, Mr. Scamander, the Care of Magical Creatures expert. How can I help you? Do you need me to cooperate with your treatment? That won't be necessary. I know my own condition..."

"Ahem." Douglas reminded them, "You're getting upset a little prematurely. I said we needed soul toxin, not that you had to die
