You know I'm gonna have the answer... LOL. It's almost creepy how much I've played/analysed this game. Annnnnyway. Here's the actual script:

Cloud (while in the lifestream)

"Tifa was in a coma for seven days."
"We all thought she wouldn't make it."
"If only I could've saved her..."
"I was so angry... Angry at myself for my weakness."
"Ever since then, I felt Tifa blamed me..."
"I got out of control... I'd get into fights not even caring who it was."

There you have it. Hope that helped. :D
