Imma piss Ryu off and respond to you even though you were responding to him.

After all, when put into perspective with the compilation (OtWtaS:CoT, Advent Children) the 'high affection' version is the only one that really makes any sense. It's logical that the ultimania, then, would reflect this.
Would that not make it canon then?

Cait Sith's prediction:
Said by the creators to be BS in the Ultima Omega... or at least they called his predictions unreliable.

Cloud's dream of Aeris in the sleeping forest: AerisxCloud implications are made when Cloud and Aeris fall slowly together to the ground, and when Cloud tries to run after Aeris as if 'pursuing her' and not wanting her to leave. I will concur, however, that there may be many different interpretations of this scene.
What about Tifa and Cloud rising slowly out of the lifestream?... does that count for CxT then? And Cloud's chasing her probably to I dunno, apologize for beating the crap out of her. Or maybe to find out where she's going.

Did you notice when Cloud wakes up he does NOT want to go after her? His friend have to convince him to do so.

The Ending: Aeris' and Cloud's souls (or whatever you want to call their out-of-body existences) reach out to each other before Cloud snaps back into reality and into his own body.
And it was Tifa's hand that was really reaching for him, wasn't it? So how can that be CxA?

So, no none of those are really CxA...
I'll let Ryu do the rest... I'm tired XD
