Constraints:
Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No invented titles, names, dates, counts, awards, ratings, box-office, viewership, or plot points.
If a detail is missing, omit it.
Style: Original, neutral, encyclopedic prose, plain text.

Word count: 280-380 words.
TMDB Episode Synopsis: Sam and Dean are searching for the First Blade and end up having to track down the missing Crowley and discover that he's now thoroughly addicted to human blood. The Winchesters decide that going cold turkey is the only way.
Series Sources:
Series title: Supernatural.
Cast: Sam Winchester (Jared Padalecki), Dean Winchester (Jensen Ackles).
Premise: Brothers Sam and Dean Winchester hunt demons, monsters, and other supernatural beings.
Sam and Dean Winchester are searching for the First Blade.
They have to track down Crowley, who is missing.
They discover Crowley is addicted to human blood.
The Winchesters decide that going cold turkey is the only way.
The provided synopsis is extremely brief (only about 45 words).
The prompt requires a 280-380 word recap.
Conflict: I cannot invent details to reach the word count. I must only use provided facts.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing."
Constraint Check: "Write a grounded 280-380 word episode recap..." vs "If the synopsis is sparse, stay concise rather than guessing."
Resolution: Usually, in these types of prompts, the word count is a target, but the "verifiable facts only" and "do not invent" rules are the primary directives. If I write 45 words, I fail the word count. If I write 300 words, I must invent things, which violates the "verifiable facts" rule.
Wait: Let me re-read the sources. Is there anything else? No.
Strategy: I will expand on the context provided by the series sources (who Sam and Dean are, what they do) to frame the episode synopsis, but I cannot add any plot details not in the synopsis.

Sam Winchester is played by Jared Padalecki.
