S6·E4 Tainted Obligation

Episode recap

Task: Write a 280-380 word episode recap for Grey's Anatomy S6E4 (Tainted Obligation).
Constraints:
Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No invented titles, names, dates, counts, awards, ratings, etc.
No guessing or inventing plot points.
Original, neutral, encyclopedic prose.
Plain text only (no markdown, no asterisks, no headings, no bullet points).
Word count: 280-380 words.
SYNOPSIS:
Meredith and Lexie's father, Thatcher, returns to the hospital with a failed liver.
Meredith must save his life.
Izzie empathizes with a patient riddled with tumors.
Mark is annoyed with Cristina's competitive zeal.
Mark tricks Cristina into assisting on an unusual surgery.
SOURCES:
[1] Series follows personal/professional lives of doctors at Seattle's Grey Sloan Memorial Hospital.
[4] Meredith Grey is a brilliant first-year surgical intern at Seattle Grace Hospital (Note: Synopsis says Grey Sloan, Source 4 says Seattle Grace. I will stick to the synopsis/source context provided).
[5] Directed by Rob Corn, Debbie Allen. Starring Ellen Pompeo, Justin Chambers, James Pickens Jr., Chandra Wilson.
The synopsis is very short.
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 "no inventing" rules.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing."
Conflict: The user asks for 280-380 words but also says "If the synopsis is sparse, stay concise rather than guessing."
Decision: I must prioritize the instruction to "only use supplied facts" and "never invent or guess." If the facts provided only allow for ~60 words, I cannot reach 280 words without violating the core instruction of being a "meticulous television and film archivist" who "never invents or guesses."
Wait, let me look closer at the sources.
Source 1/3/5 mentions Grey Sloan Memorial Hospital.
Source 4 mentions Seattle Grace Hospital.
Source 5 mentions directors Rob Corn and Debbie Allen.
Source 5 mentions actors Ellen Pompeo, Justin Chambers, James Pickens Jr., and Chandra Wilson.
Synopsis mentions Meredith, Lexie, Thatcher, Izzie, Mark, and Cristina.
