Tracey tried to take the stairs quickly, but it was difficult. Carrying Timmy and simultaneously trying to pull Rick along was almost impossible. Rick wasn't deliberately resisting, but he was utterly confused. His darting, frightened eyes showed he was only vaguely aware that they were trying to escape this evil building that was somehow inside their heads, causing hallucinations. He moved slowly and ungainly, each step a deliberate exercise in not falling over, in not crumpling in a bewildered mess to the floor.
Effort and fear coated her body in sweat; and, panting, she almost fell the last few stairs.
