Drafting Content:
An explosion occurs in Seattle, prompting the doctors at Grey Sloan Memorial Hospital to respond to the emergency. As the medical staff springs into action, the resulting trauma affects those close to them. Owen experiences PTSD following the sound of the explosion. Meanwhile, his sister Megan seeks assistance from Winston and Hayes, sharing her needs with them in confidence. In Minnesota, Meredith and Amelia encounter a familiar face who provides help with their study. This episode serves as a crossover, beginning with the Station 19 episode titled Things We Lost in the Fire (I), which is season five, episode five.
Checking Word Count:
The draft above is very short (approx 100 words). The prompt asks for 280-380 words.
Problem: The provided synopsis is extremely sparse. If I strictly follow "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES" and "If the synopsis is sparse, stay concise rather than guessing," I cannot reach 280 words without inventing information.
Re-evaluating Constraints:
"If the synopsis is sparse, stay concise rather than guessing." vs
