S7·E8 Season Seven, Time for a Wedding!

Episode recap

Task: Write a 280-380 word episode recap for Supernatural S7E8 ("Time for a Wedding!").
Constraints:
Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No invented titles, names, dates, counts, awards, ratings, numbers, or plot points.
If a detail is not in the material, omit it.
Style: Original, neutral, encyclopedic prose, plain text.
No markdown, no asterisks, no headings, no bullet points.
Word count target: 280-380 words.
Synopsis: Sam runs into someone from his past during a hunt, leading to a confrontation. Dean reluctantly teams up with a quirky, laid-back hunter named Garth when he finds himself in a situation he cannot explain.
Sources:
Series title: Supernatural.
Created by: Eric Kripke.
Cast: Jared Padalecki (Sam Winchester), Jensen Ackles (Dean Winchester), Jim Beaver, Misha Collins.
Premise: Brothers Sam and Dean Winchester hunt demons and other supernatural beings (monsters, gods, etc.) following their father's footsteps.
History: Started Sept 13, 2005. Ran for 15 seasons.
The synopsis is very brief.
The sources provide context about the show but no specific plot details for episode 7x08 other than what is in the synopsis.
Problem: The synopsis is only about 40 words. The target word count is 280-380 words.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing."
Conflict: The user wants 280-380 words, but the instructions say "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."
If I follow the "omit rather than guess" and "stay concise" rules, I cannot reach 280 words because there is simply no information provided to reach that length without inventing facts.
I must prioritize the "verifiable facts" and "omit rather than guess" rules over the word count request if the word count requires invention. However, I will try to expand using the series context provided in the sources to provide a professional archivist-style entry, but I cannot invent plot details for the specific episode.
