S8·E9 Citizen Fang

Episode recap

Task: Write a 280-380 word episode recap for Supernatural S8E9 (Citizen Fang).
Constraints:
Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No invented titles, names, dates, counts, awards, ratings, etc.
No guessing or inventing plot points.
Original, neutral, encyclopedic prose.
Plain text only (no markdown, no asterisks, no headings, no bullet points).
Word count: 280-380 words.
Synopsis: Sam asks a hunter named Martin to keep an eye on Benny without telling Dean. Martin tells Sam and Dean there was a vampire kill and that Benny is responsible. Dean defends his friend.
Sources:
[1] TMDB: Series overview (Saving people, hunting things, the family business).
[2] Wikipedia: Series ran 15 seasons (Sept 13, 2005 - Nov 19, 2020). Stars Jared Padalecki (Sam) and Jensen Ackles (Dean).

The synopsis is extremely sparse. It only mentions:
Sam asks Martin (a hunter) to watch Benny.
Sam does this without telling Dean.
Martin tells Sam and Dean about a vampire kill.
Martin says Benny is responsible.
Dean defends Benny.
Problem: The word count requirement is 280-380 words. The provided synopsis is only about 40 words.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing."
Conflict: The user asks for 280-380 words, but the instructions say "If the synopsis is sparse, stay concise rather than guessing" and "Never invent or guess... plot points."
Resolution: I cannot fulfill the 280-380 word count requirement without violating the "never invent or guess" and "use only supplied facts" rules. If I write 280 words based on a 40-word synopsis, I will be inventing details.
Strategy: I must prioritize the "verifiable facts" and "never invent" rules. However, as an AI, I should try to expand the context using the Sources provided to reach a reasonable length, but the sources only provide series-level info, not episode-level info.
Available Facts for Expansion:
