Tristan speaking to Jake? Didn't you mean Hawk? Anyway, if I recall correctly, I think both those have been translated.
Also, Twilkitri wrote a list of what still needs to be done (you should be able to find it on FESS.)
Apart from that, I think some village conversations aren't translated in the FE5 patch (chapter 20 for sure, and possibly the ones in the following chapters).
