S10·E7 Thriller

Episode recap

Task: Write a 280-380 word episode recap for Grey's Anatomy S10E7 (Thriller).
Constraint 1: Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
Constraint 2: No invented titles, names, dates, counts, awards, ratings, etc.
Constraint 3: Original, neutral, encyclopedic prose in plain text.
Constraint 4: No markdown, no asterisks, no headings, no bullet points.
Constraint 5: If the synopsis is sparse, stay concise (but the prompt asks for 280-380 words, which is a contradiction if the synopsis is very short. I must try to meet the word count if possible, but the primary rule is "never invent or guess").
Constraint 6: Do not add dialogue, scene order, character names, or plot events not explicitly present.
Synopsis: "Costumed patients create a challenge for the doctors; Derek and Ben work on a new surgical technique; Richard asks a resident to perform his next surgery, angering Bailey."

The synopsis is extremely brief.
The prompt asks for 280-380 words.
The instruction says: "If the synopsis is sparse, stay concise rather than guessing." and "Never invent or guess... plot points."
If I strictly follow "Never invent or guess," I cannot reach 280 words because there are only about 40 words of plot information provided.
If I try to reach 280 words by repeating the same facts or adding fluff, I might violate the "encyclopedic prose" and "neutral" instructions.
However, I can expand on the context provided by the sources (the show's setting, the nature of the series, the names of the actors/directors/creators) to provide a more
