But we see Malon as an adult moments after Link is set back. If MM happens during the seven years that Hyrule is under Ganondorf's rule, then the celebration at the end wouldn't make sense. A split timeline is a cleaner way to explain it.

2. How is Ganon in FSA the same one as in OoT? How does he even comeback after being eradicated by the Triforce in TWW?
Everyone else has covered what I was...
