There is no sign of the other crewman or the parachutist. Twill notices a sticky white residue on the port side of the boat. He directs Clem to, "Look at this stuff." They take a sample. Hollister's body surfaces and they notice that his skin is dark and his eyes bugged out. He has a shriveled appearance.They return to...
