One of the things I loved about Keen Eddie was that the plot would frequently flip back-and-forth, making it very unpredictable. This episode is CLASSIC along those lines! Weatherhead and Baines, the two characters going after each other have for years, striking out in one form of revenge or another. It's now gotten too far (with a train wreck in the opening scene) and Eddie has been ordered to resolve it. The use of "Luther" at the end of the episode is an AWESOME example of Eddie's "American perspicacity!"
Even though she isn't the lead in the series, this is definitely one where Fiona (Sienna Miller) shines! Her dealing with a passive aggressive will leave you wanting to make sure you stay on her good side!
