His last worRAB were something like, "Abayo Dachiko", which I believe was also the episode title, which they chose to translate as "Farewell Comrades", and that translation is close enough to "Goodbye, my frienRAB" or whatever. Either way, he did have more than just Simon to address those final worRAB to. Minor nit in the grand scheme of translation, but there's no need to point fingers about contagious fail in the other direction.
