Stone ascertains that the creature must exist in only two dimensions, as when he turns sideways he becomes invisible, and is able to move through walls. Stone visits his physicist brother to talk over the idea, but his brother dismisses him as mad. Dr. Stone has his secretary order several new pairs of the meteoric eyepieces, and tries to track down the patients sought by the two-dimensional creature. One has been injured, another is found dead, and the third, a welder, managed to ward off the creature with his welding torch (later Stone is told by the creature that in the second dimension, fire is all-powerful because two-dimensional organisms, like dry leaves or paper, are easily set aflame). It is also discovered that a large building has been cut in half. Stone's brother and the police begin to investigate these occurrences. Meanwhile, in the excitement of the moment, Stone suddenly seems to notice the love-struck Ms. Dunn for the first time, remarking after putting on a different pair of glasses that something about her "looks different," as she glows with adoration towards him.
