Again - Kowalski NEVER called Fraser "Benny" on the show, and there's no reason why he would start doing in an AU story when he's Fraser's lover.
Please show some respect for RayV and the F/V shippers and have only RayV saying "Benny!" And if you have to use "Benny" to make the case for F/K, then F/K isn't a realistic pairing. I got disgusted when I started reading this story and realized that the person saying "Benny" was Kowalski and not RayV, because it really looks like you're trying to erase RayV from the show. Did you forget that dS would not have been renewed if it wasn't for the fans adoring RayV and Fraser's friendship?
