He smiled. "The Investors searched me very thoroughly, including X-rays. But the vein appears normal to X-rays, and the bacteria are trapped within compartments in the vein. They are indetectable. I have a small medical kit on my person. It includes a syringe. We can use it to extract the pheromones and test them. When the tests are finished—and I feel sure they will be successful, in fact I’ve staked my career on it—we can empty the vein and all its compartments. The bacteria will die on contact with air. We can refill the vein with the yolk from a developing embryo. The cells may survive during the trip back, but even if they die, they can’t rot inside my body. They’ll never come in contact with any agent of decay. Back in the Rings, we can learn to activate and suppress different genes to produce the different castes, just as is done in nature. We’ll have millions of workers, armies of warriors if need be, perhaps even organic rocket-ships, grown from altered alates. If this works, who do you think will remember me then, eh? Me and my arrogant little life and little sacrifice?"
