Sources:

The synopsis is extremely brief:
1. Sam and Dean are stunned by Castiel's sudden appearance on Earth.
2. Castiel has no memory of how he escaped Purgatory.
3. Mrs. Tran enlists a witch to make a demon bomb.
The sources provide context about the show (creators, actors, general premise), but very little about this specific episode.
Problem: The synopsis is only about 35 words. The target word count is 280-380 words.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing."
Conflict: The user wants a 280-380 word recap, but the instructions say "If the synopsis is sparse, stay concise rather than guessing" and "Use only supplied facts."
Resolution: I cannot fulfill the 280-380 word requirement without inventing facts, which is strictly forbidden by the primary instruction ("You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. You never invent or guess..."). If I write 300 words based on a 35-word synopsis,
