Task: Write a 280-380 word episode recap for Grey's Anatomy S13E21 ("Don't Stop Me Now").
Role: Meticulous television and film archivist.

Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No invented/guessed titles, names, dates, counts, awards, ratings, etc.
If a detail is not in the material, omit it.
Original, neutral, encyclopedic prose.
Plain text ONLY (no markdown, no asterisks, no headings, no bullet points).
Word count target: 280-380 words.
SYNOPSIS: "Bailey and April work to fix things between Richard and Catherine; Eliza continues to pursue Arizona; one of Alex's previous patients returns to Grey Sloan."
SOURCES:

Episode Number: Season 13, Episode 21.

The synopsis is extremely brief.
The word count requirement is 280-380 words.
Problem: If I only use the provided facts, I cannot reach 280 words without repeating myself or adding fluff, which violates the "neutral, encyclopedic prose" and "never invent or guess" rules.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing."
Conflict: The user asks for 280-380 words, but the provided material only contains about 30 words of actual plot content.
Strategy: I must provide the facts available. If I cannot reach the word count without violating the "no guessing/no inventing" rule, I must prioritize the "verifiable facts" and "omit if not in material" rules. However, I can expand on the context of the series provided in the sources to build the "encyclopedic" feel.
