Uncomprehending, they stood motionless. The Doctor's gaze was at the rocky floor under his feet.
"It's size," he added vehemently. "Don't you understand? He's taken too much of the diminishing drug."
An exclamation from Oteo made them all move towards him, in spite of the Doctor's command. There, close by Oteo's feet, they saw the tiny figure of the Very Young Man, already no more than an inch in height, and rapidly growing smaller.
The Doctor bent down, and the little figure waved its arms in terror.
"Don't get smaller," called the Doctor. But even as he said it, he realized it was a futile command.
The Very Young Man answered, in a voice so minute it seemed coming from an infinite distance.
"I can't stop! I haven't any of the other drug!"
They all remembered then. Targo had stolen the Very Young Man's vial of the enlarging drug. It had never been replaced. Instead the Very Young Man had been borrowing from the others as he went along.
The Big Business Man was seized with sudden panic.
"He'll get lost. We must get smaller with him." He turned sidewise, and stumbling over a rock almost crushed the Very Young Man with the step he took to recover his balance.
