Stewart's mistake in sharing information with Rob in Shattering Glass is that Rob is an intern at the magazine and Stewart is a higher-level reporter or editor. By sharing information with Rob that could be considered confidential or exclusive, Stewart is potentially compromising his own position and reputation, as well as the credibility and integrity of the magazine. It also raises questions about whether Stewart is exercising proper editorial judgment and following ethical journalistic practices by sharing information with a less experienced colleague who may not have the same level of understanding of the implications of such actions.
