Know what I don't understand? How CloudxTifa fans can think that Cloud's only feelings toward Aeris were guilt.
He was emo to the max! Asking HER to forgive him, but not Zack. And besides, when he thought that Tifa had died in FFVII did he suffer remorse that profound? Did he give a huge speech in tears about how she would never "laugh, cry or get angry again?" No. He moved her out of the way, she was happy he'd come, then he moved on to Sephiroth. That was it.

My anti-Cloti sigs were never that impressive, but I had fun
