Frankly a translation could be incredibly close to the Japanese version since you can see that internet subbers usually manage to get the correct translations.
That argument is mute unless there were never many changes in phrases and their meanings.
Perhaps they wanted to just add facts to the game. Like how the NoA translaters hinted at MidnaxLink when at the end of TP they change:
"Link...s...see you."
to
"Link... I... See you later."
Um Dark_Link... that was a mistranslation. It sorta went something like "evil demon" or something, I can't find the post that told me this exactly but I know it is a mistranslation.
No, I just said incarnations. Different from the oracles of Seasons and Time unless you have proof Mr. Wright. Because if this did take place before OoX, the existance of the Triforce would have been known.
Honestly, these girls seem more like incarnations of their OOX parts. They have no real power according to me since they can't control the Seasons or Time.
