Barrington shakes the man's hand, sealing the deal, and then exhales. "It's a pleasure doing business with you, and of course any future business will come your way."
He's pleased with the deal, but knows this is only the start. He nods at Kid, a tight wry smile on his face, and asks, "Thank you, too. Care to help me now for the rest of the day?" Barrington's hoping for a yes, and he thinks Kid will be able to help him with what he has in mind.
He unslings his pack, and carefully removes four packages. Three contain coins: 50 pounds each, a mixture of notes and coins, tightly wrapped so that they do not clink, in inexpensive paper and string, or in once case within a tightly tied kerchief. It should not be obvious that these are the only such packages he possesses, but that's only because he wants to give the appearance of comfort and prosperity even when it is not actually there. The remaining ten pounds he removes from his wallet.
As he gives them to Roy (or whoever within Roy's sight is willing to take them, he turns, as if looking for more information. "Do you have a man in town through whom I can relay messages? Or would you prefer them to come here?" Once he has his answer, he nods, and continues, "That is how I shall make final payment and see to delivery of the demiculverins."
The fourth package is different. The corners are squared, and the oilskin wrap is clearly protecting something from external damage. Barrington undoes the knot of the leather cord that wraps it twice winding it around his fingers as he does so. The waterproofing is scratched from use, but the protection it offers has been effective for the notebook within looks pristine, and therefore out of place in the subterranean cavern.
"I think we'll be fine without the wagon," says Barrington, somewhat embarrassed by the show he is about to make of himself. While Komodo Roy's people are gathering the shot and the Mary Sue, and the limes, Barrington reviews his notes and draws a well of ether together in a concave nexus. The process takes several minutes, but once he has done so, he begins to sculpt the ether into a shield of sorts, that becomes increasingly circular (shimmering lights floating in the air and gradually taking on a disk-like appearance, to any nearby who would see). When the disk is ready, Barrington loads it up, and makes his way out of the cave, saying "Thank you, kindly" to anyone who escorts him out of Komodo Roy's lair.
As he walks along the beach (with Kid, presumably), and back towards Nassau in the early afternoon sun, Barrington avoids answering the most obvious question, and instead says, "That seemed to go very well. Why don't we try to get some food in you now?"
[[OOC: cast Tenser's Floating Disk as a ritual while material is gathered. He feels he is safe here (at least until the promised 250 gp are paid), and he wants to gauge the reaction of the men who work with Roy to the spell casting. Ideally that will carry the swivel gun, its shot, and the limes. It will carry 500#; perhaps that's enough to allow Kid to ride on it too if he likes.]].
