The synopsis is extremely brief.
The sources provide context about the series (creators, actors, general premise) but very little about this specific episode.
Problem: The synopsis only contains about 45 words of plot information. The word count requirement is 280-380 words.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." and "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES."
