I know what scene he's talking about. It's after Cloud comes to terms with the fact that he never actually made it to SOLDIER and he came back with Zack and Company. Zack got his ass handed to him after Sephiroth stabbed Tifa and Cloud bursts in chases Sephiroth gets stabbed and lifts Sephiroth up by the sword (I should remark that Sephiroth's defeat came from his inability to let go of a sword that obviously wasn't doing any good) that is still impaled in his tummy and throws him. This is because just because and I don't remember it ever being explained as anything more than CLOUD R STRONG.
