I would have been completely alright with them changing up the ending and having Diaval try True Love’s Kiss on Aurora. You can tell just by the look on his face when Maleficent said that there was no such thing as true love, how shocked/hurt he seemed, I think he believes in it.
Plus if they were going to have the kiss be romantic love instead of the maternal true love like what we got, Diaval would have made more sense than Phillip. Phillip’s kiss didn’t work because he and Aurora weren’t actually in love, they hadn’t had time to fall in love! That’s why in the movie it was Maleficent’s kiss because she had formed such a strong loving bond with Aurora over the years. Diaval had also spent so many years with Aurora (16 to be exact), and they actually had time to form a relationship. It could have worked.
Sorry Prince Phillip, but I have to say I prefer my Raven Prince…ooh dear, I believe I just gave myself fic ideas.
