Episode recap

Topic: Episode recap for Grey's Anatomy S7E13 ("Don't Deceive Me (Please Don't Go)").
Constraints:
Write ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No invented titles, names, dates, counts, awards, ratings, etc.
No guessing or inventing plot points.

Sources: General series info (Seattle's Grey Sloan Memorial Hospital, creator Shonda Rhimes, etc.).

The synopsis is very short. The word count requirement is 280-380 words.
Problem: If I only use the provided facts, I will struggle to reach 280 words without being repetitive or "guessing."

Conflict Resolution: If I follow "stay concise rather than guessing," I will fail the word count. If I follow the word count, I might have to repeat facts or use the series context.
Refined Strategy: I will use the series context (Grey Sloan Memorial Hospital, medical drama, Shonda Rhimes) to build the prose, but the actual episode content is limited. I will describe the events of the episode as presented.
