S22·E9 Fortunate Son

Episode recap

Task: Write an episode recap for Grey's Anatomy S22E9 (Fortunate Son).
Constraints:
Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
Do not invent/guess titles, names, dates, etc.
Write original, neutral, encyclopedic prose.
Format: Plain text only (no markdown, no asterisks, no headings, no bullet points).
Word count: 280-380 words.
Tone: Grounded, meticulous archivist.
Synopsis: "Richard continues to navigate his health. Meanwhile, Meredith and Nick are visited by Nick's estranged sister from Boston."
Sources:
[1] General info: Grey's Anatomy (2005), TV-14, Drama, follows doctors at Seattle's Grey Sloan Memorial Hospital.
[2] Cast/crew info (no specific details for this episode).
[3] Cast/crew info (no specific details for this episode).
[4] General info: Meredith Grey is a surgical intern (though the series has progressed, this is the general premise provided).
[5] General info: Starring Ellen Pompeo, Justin Chambers, James Pickens Jr., Chandra Wilson.
Episode Title: Fortunate Son.
Episode Number: S22E9.
Plot Point 1: Richard continues to navigate his health.
Plot Point 2: Meredith and Nick are visited by Nick's estranged sister from Boston.
The synopsis is extremely sparse.
The word count requirement is 280-380 words.
Problem: If I only use the provided facts, I only have two sentences of plot.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." vs "Write a grounded 280-380 word episode recap".
Conflict Resolution: As an archivist, I cannot invent facts to meet a word count. However, I must follow the instruction "Write a grounded 280-380 word episode recap". If the provided material does not allow for 280 words without violating the "never invent or guess" rule, I am in a bind.
Wait, looking at the prompt again: "If a detail is not in the provided material, you omit it rather than guess." and "If the synopsis is sparse, stay concise rather than guessing."
This implies that if the source material is too short to reach 280 words, I should not fluff it with lies. But the prompt demands 280-380 words.
Let's see if I can expand using the general series info provided.
