The crowd will turn against Steve, believing he is an alien in disguise.
Explanation:
<em>The Monsters are Due on Maple Street</em> by Rod Sterling tells the fictional story of how a community began to suspect their neighbors of being aliens who came to spy on humans. Aided by Tommy's story of how an alien group resided as a family to spy over mankind, the people began to check out the suspicious people they believe could be an alien.
From the given conversation between Don and Steve, we can infer that the people had begun to be suspicious of his lifestyle. Added to that, his own wife had also admitted that he'd <em>"spend hours down in your basement workin' on some kind of radio or something"</em> which none had seen.
The given excerpt shows that the people will suspect Steve of being an alien in disguise and turn against him.
