Task: Write a 280-380 word episode recap for Supernatural S15E7 (Last Call).

Constraint 2: Do not invent/guess titles, names, dates, counts, awards, ratings, etc.
Constraint 3: If a detail is not in the material, omit it.
Constraint 4: Write original, neutral, encyclopedic prose in plain text.

Synopsis: "Dean goes off on his own to take on a case. Meanwhile, Castiel has an idea of how he can help Sam track down God."
Sources:
[1] TMDB: Series title Supernatural (2005). Tagline: "Saving people, hunting things, the family business."
[2] IMDb: Cast and crew credits.
[3] Wikipedia: Created by Eric Kripke. Broadcast on The WB and The CW for 15 seasons (Sept 13, 2005, to Nov 19, 2020). Follows Sam (Jared Padalecki) and Dean (Jensen Ackles).

The synopsis is extremely brief: Dean goes on a case alone. Castiel has an idea to help Sam find God.
The sources provide context about the series: Sam and Dean Winchester are brothers, the series is a dark fantasy/horror/drama, it ran for 15 seasons, etc.
Problem: The synopsis is only two sentences long. The requirement is 280-380 words.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." vs "Write a grounded 280-380 word episode recap".
Conflict: I cannot reach 280 words without inventing details, which is strictly forbidden ("You never invent or guess... plot points").
Strategy: I must provide all the facts available in the synopsis and the series context provided in the sources, but I cannot fulfill the word count requirement without violating the "never invent or guess" rule.
Wait: Let me re-read the prompt. "Write a grounded 280-380 word episode recap... Use only supplied facts. Never add dialogue, scene order, character names or plot events not explicitly
