Maybe…but I don’t think that would make us, as watchers, really feel the sense of “I basically understand only 2% of what they are saying” that Haru is going through right now (and probably what a lot of Japanese fans and watchers would be going through too if they didn’t have subtitles or something on the episode…I’m going to assume they did though. After all, the episode used a lot of colloquial English, and Rin’s “hotter than hell” line is used correctly (it is an expression that doesn’t seem to be used all that much or doesn’t seem to be all that well known in Japan. The “than hell” part is a very colloquial way of saying “very/extremely”). In order to recreate this feeling for English viewers, I really do think they would need to go the “made up language route.”Futhermore, this episode was all about Haru realizing just how not free he was back in Japan, and him lacking English language abilities is one aspect of that. Rin knows English, that gives him a type of freedom that many Japanese don’t have due to their lacking English language skills. I remember talking to my Japanese friend during one of our language exchanges, and she told me that I was really lucky to be a native English speaker, and she’s right. You can go to basically any heavy tourist area and there will be English, movement and travel and understanding…it all just becomes an easier and freer thing for English speakers. There’s also the fact that most of those scenes, with Rin speaking English (the exception being when Rin is talking with the receptionist, are shown from Haru’s POV, a lot of this episode is, since it deals with Haru taking everything in and finally realizing his dream.I can’t really see the above aspects being properly translated over into an English dub if they still use English for Rin’s conversations with the native English speakers and such. Of course, I’m not a member of the actual dubbing company (if there is ever going to be one for Free!), so I can only speculate and guess (and think about what I would do in this situation as a future -official- translator - I want to be one someday!)
