S12·E21 Chap Stewie

Episode recap

Topic: Episode recap for Family Guy S12E21 (Chap Stewie).
Constraints:
Write ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No inventing/guessing titles, names, dates, etc.
Original, neutral, encyclopedic prose.
Plain text only (no markdown, no asterisks, no headings, no bullet points).
Word count: 280-380 words.
If details are missing, omit them rather than guessing.
SYNOPSIS: Peter and Chris interrupt Stewie's TV time. Stewie goes back in time to break up Peter and Lois so he is never conceived. He is reborn into a "Downton Abbey"-esque British household.
SOURCES:
[1] Series title: Family Guy (1999).
[3] Network: Fox Network. Genre: Animation, Comedy.
[4] Characters: Peter, Lois, Stewie, Meg.
[5] Creator: Seth MacFarlane.
The synopsis is very brief.
The sources provide general series info but very little specific episode info beyond the synopsis.
The prompt asks for a 280-380 word recap.
Problem: The provided synopsis is only about 45 words. The sources do not contain any additional plot details for S12E21.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." and "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES."
If I strictly follow the instruction "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES," I cannot reach 280-380 words without inventing information, which is strictly forbidden.
However, the prompt also says "Write a grounded 280-380 word episode recap".
This is a conflict. If I write 280 words, I am inventing. If I write only what is provided, I will be around 50 words.
Decision: In professional archiving/fact-based writing, accuracy is paramount. I must prioritize the instruction "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES" and "If a detail is not in the provided material, you omit it rather than guess."
Wait, let me re-read. Is there any other info?
Sources mention: Family Guy is an animated comedy series created by Seth MacFarlane. It airs on the Fox Network. The characters include Peter, Lois, Stewie, and Meg.
The episode "Chap Stewie" involves Stewie traveling back in time.
