Theory: After getting shot, Cloud takes Zack's sword (yada, yada, you know the story)... *fast-forwards through the Cloud getting angsty, until he leaves*
...'Kay. Actually, Zack was still alive, and he got carted back to Shin-Ra by God-knows-who (>>) and, well, yeah. So he's still in SOLDIER.
[end of theory]
...So, like, I'm wondering if he should still have his memory or not. If he still has it, then what is he gonna do about Cloud? 'Cause to him, it's like - Cloud's all "aa... gurk", and suddenly Cloud disappeared and he's back in Shin-Ra and keeps hearing news about Cloud being sighted, and about AVALANCHE. If he lost it, well... that would be downright SAD. That means that he can still look at Hojo and not hate him. That means that he'll be - "Cloud who?" and... Damn, I want to cry.
