"You mentioned fabric, I can go to a fabric store, how many bolts are we talking here?"
She departs.
She comes back with a big bin that looks like it might be supposed to carry laundry, full of natural fibers that were on sale.
She looks over the circle drawing, finds nothing she needs to ask questions about, and shoos him.
She resummons him the following morning. The circle is drawn very exactly on the floor of the cell he's been occupying.
"Morning. I got you breakfast." She indicates breakfast. "What'd you bring?"
"All sorts of good stuff. Two dozen modular computers, a swarm of little drones, a proper 3-D printer, the real prize is an industrial-size monoatom deposition beam," he motions at the largest bundle. "Might not sound impressive but if I get some raw materials from a changer and factory space from USADI I'll have fifteen UV flashlights a minute rolling off a line in four days."
"Sweet. I guess I should go summon a changer then. Wanna help me work out a rude proposal to leave in the circle?"
Bella mostly proves willing to accept Nick's direction on the wording of the rude proposal.
And she carries it off, presumably to fill tubs with water and get his shopping list.
And Bella summons an angel, and the angel tolerates her rudeness, and accepts the exchange.
Bella wheels in the first tub of stuff, looking smug.
