Tarpon is the submarine that has been bringing them ammunition, medical supplies, I SHALL RETURN stickers, cartons of American cigarettes with I SHALL RETURN inserts in each pack, I SHALL RETURN matchbooks, I SHALL RETURN coasters, and I SHALL RETURN condoms. Shaftoe has been stockpiling the condoms because he knows they won’t go over well in a Catholic country. He figures that when he finds Glory he’ll go through a long ton of condoms in about a week.
