Fuchs: There's something wrong with Blair. He's locked himself in his room and he won't answer the door, so I took one of his notebooks from the lab. MacReady: Yeah? Fuchs: Listen: "It could have imitated a million life-forms on a million planets. It could change into any one of them at any time. Now, it wants life-forms on Earth." MacReady: It's gettin' cold in here, Fuchs, and I haven't slept for two days. Fuchs: Wait a minute, Mac, wait a minute. [reads from the book] Fuchs: "It needs to be alone and in close proximity with the life-form to be absorbed. The chameleon strikes in the dark." MacReady: So is Blair cracking up or what? Fuchs: Damn it, MacReady! [reading from the notebook] Fuchs: "There is still cellular activity in these burned remains. They're not dead yet!"
