Worthless plastic container holding Paulie's containment device, traded away after half an hour of haggling.
Carl and Orren spend half an hour negotiating over all the stuff Carl could and could not have in exchange for Paulie's worthless, plastic tub — and the whole time Carl keeps thinking, what difference does this make? What difference does any of it make?
The trade nonetheless delivers the Containment Interface, installed as a new tab moments after the haggling ends. Carl half regrets consenting to the installation almost immediately; Paulie's warning has gotten to him, and he sits in The Gas Station wondering whether humanity is worth saving, or worth sacrificing.
A cheap, ordinary plastic tub, described flatly as worthless.
The unremarkable object that carried the only leverage anyone has held over the dungeon AI.
