The synopsis for S7E23 is extremely brief: "When a colleague's murder sends shockwaves through the team, Gibbs uncovers a surprising link to the crime."
The sources provide general series information (creators, cast, premise) but do not provide specific plot details for Season 7, Episode 23, other than what is in the synopsis.
The prompt asks for a 280-380 word recap.
Problem: The provided synopsis is only one sentence long. If I strictly follow the instruction "If a detail is not in the provided material, you omit it rather than guess," I cannot reach 280 words without repeating myself or adding information not in the text.
Constraint Check: "Write a grounded 280-380 word episode recap... Use only supplied facts. Never add dialogue, scene order, character names or plot events not explicitly present. If the synopsis is sparse, stay concise rather than guessing."
