Episode Title: If Walls Could Talk.
Episode Number: S21E1.
Hospital: Grey Sloan Memorial Hospital.
Characters mentioned in synopsis: Catherine, Meredith, Amelia, Bailey.
Plot Point 1: Catherine has fired some of Grey Sloan's best staff.
Plot Point 2: Catherine continues to interfere with research conducted by Meredith and Amelia.
Plot Point 3: Accidents occurring at a climate change protest result in unique cases arriving at the hospital.
Plot Point 4: Bailey encounters a blast from her past.
The synopsis is very short. The word count requirement is 280-380 words.
Problem: The provided synopsis only contains about 40 words of actual plot information.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." AND "Write a grounded 280-380 word episode recap."
Conflict: I cannot reach 280 words without inventing details, which is strictly forbidden ("You never invent or guess... If a detail is not in the provided material, you omit it rather than guess").
Resolution: I must follow the instruction "If a detail is not in the provided material, you omit it rather than guess." However, the prompt also asks for a 280-380 word recap. Usually, in these types of prompts, if the source material is insufficient to meet the word count, the "do not invent" rule takes precedence over the "word count" rule to maintain accuracy. However, I will try to expand on the context
