Malcolm stared at the man. "Kind of not human" might translate as "human, but off my rocker", or "alien, and plotting something", or, of course, "alien and off my rocker". None of the possibilities did anything to put Malcolm's mind at ease.

He let go of the man, scrambled out of bed and ran over to the intercom.

"Reed to Security."

Silence. Malcolm hit the button again.

"Security, respond!"

The intercom was quite obviously dead. Which meant that the man had sabotaged it. Which meant that "alien and plotting something" was rather close to the mark, after all.

Malcolm turned to the man. "Stay where you are."
