Aeris is Zack's girl, man. That's just plain unethical to go for your (dead) friend's girl. If you think about it, Cloud went to the "ends of the earth" for Aeris only because the whole group decided it would be a good idea. Aeris was a self-righteous bitch anyways. All she wanted to do was perform her "duties as a cetra" to protect the planet and all that other shite. She didn't give a shrivelled rat's ass about Cloud and everyone else. Honestly, name one time where Aeris saves Cloud's arse. Never. AFAIK, Aeris was just tagging along as a roadie so she could take out Cloud when she had the chance. Why else do you think they cut the scene where Aeris pulls a knife and threatens Cloud during their possible date? She will do anything to get her way. Look, I have proof of it happening!
Aeris pulls a knife on CloudThe only part of Cloud Aeris liked was the Zack part. Cloud assimilated his behavior and personality from Zack, and that's the only reason why Aeris liked him. Sure, she wanted to get to know the real Cloud, but it was for friendly purposes. Or so you're led to believe. She didn't like him. He crushed her flowers. He brought the turks to her church. So she got him back by making him dress up as a lady. She ran away and got caught by Shinra
on purpose so that Cloud and everyone would feel sorry for her. She could have tried to protect herself from the part where Cloud goes berserk on her in the temple of the ancients, but once again she took the pain for some extra emotional leverage in the courts. So finally she jacks the keys for the tiny bronco and leaves to the forgotten capital and somehow manages to get the plane back in time before anyone notices. So she has a long time to get ready in the forgotten capital. A few auto-spraying blood packets here and there, a harness for the guy dressed up as sephiroth to do those amazing spin moves, and the stage is set. Aeris' body double takes a fake sword through the back, no one is hurt.
That's what really happened, but it was cut out of the original game
My conclusion: Cloud and Aeris were
not meant for each other. Despite the utter bullshit evidence above, it still remains that:
The only part of Cloud Aeris liked was the Zack part. Cloud assimilated his behavior and personality from Zack, and that's the only reason why Aeris liked him.
And Tifa and Cloud were meant to be together because they have known each other since childhood, they both survived a terrible incident which brought them together closer, and why else did Tifa come along with Cloud anyways? She likes him. Aeris may have liked the "Zack Factor" of Cloud, but ultimately her eye was kept on the prize; casting Holy.
