Get out of Exiled Player Gaming

No one could ever confirm to me that Marin didn't mess up her original wish and that her real wish would have been to go back with Link.
Not to mention the implication that it may have been more than just a dream. Because if it was just a dream then how did she become a seagull?
Making the implication that the word dream is linguistic slack fill for: being made of the magic of the wind fish sleeping. So the wind fish lied to you trick you into doing a genocide.
Plus we have the double slit experiment plot hole effect where in 1 ending she dies and in the other she becomes a seagull and said she was going to sing for the whole world. Okay? Then where's her song?! No where in cannon does her song ever play again implying that the "real" ending is that she just died!
I NEED PROOF PROOF SHE IS OK!
