It is speculated by some that alternate worlds such as the Twilight Realm and Termina may be unaffected by the timeline split. However, while these two realms are alternate dimensions, there is no evidence to support the idea that they exist outside of linear time. Both realms have demonstrated the ability to receive beings from the Child Timeline and return them to the Child Timeline when they exit back into Hyrule. There is no reason to believe that these two realms would only exist as a single timeline, or that they could "prioritize" inputs from one timeline, and later output these into both the timelines.
In addition, the renowned Youtube show, Game Theory, dismissed the Zelda Timeline, particularly the Defeat Timeline (in where Link fails on his quest) on the grounds that "the hero cannot be simultaneously victorious and defeated". Elaborating, he explained that with Link defeating Gannondorf, two perfectly possible timelines are created; However if Link dies at any point in his journey another separate timeline is created. Explaining that the only way for all 3 timelines to exist is the Many Worlds Theory (the theory that all possible pasts and futures exist in separate timelines).
TalonEditAs Malon is confirmed to have been based on Marin, a character from The Legend of Zelda: Link's Awakening, it is assumed that Talon is based on Marin's father, Tarin, from the same game. Both are reminiscent in appearance to Mario, and their daughters share many similarities as well.
In The Legend Of Zelda: Ocarina Of Time, Talon gives an interesting reaction to the Gerudo Mask if Link approaches him as a child while wearing it, saying that it looks like his wife, but then decides against it. This reaction hints Malon's mother has Gerudo ancestry. This would explain Malon's vibrant red hair, which appears to be a recessive trait among most Hylians. This has never been confirmed by Nintendo.
