The yeerk snorted, looking at him. "I survived two years of the undercover invasion without blowing my cover, Sub Visser 26, do you think I will suddenly lose all pretense of subtlety and go up to the next human I see and introduce myself as a parasite? I am more than capable of keeping my mouth well and truly closed. And I have good control of my host, there will be no episodes of host rebellion that might blow my cover. It's the same game in a different playing field and the stakes are just as high."

He was really unconcerned, he had played this game surrounded by people who knew his host and hadn't failed, here on a ship full of strangers...well, that much easier to let the mask slip and little and define himself as someone aside from a likable but a bit dense high-school student.

"It would likely be better if we limited contact with each other as well, though it is convient to know we don't need to leave our hosts, lessens chances of being discovered if they know the feeding cycle."
