Why doesn't the camera follow Cloud? That's a flaw. What about the damage around Jenova's container? That's a flaw. How did Cloud get out? That's a flaw. If he broke out, why isn't there similar damage to the cell door? That's a flaw.
Jenova getting out herself has one assumption. No flaws.
Jenova did not have to open Cloud's door though. It could have been opened by that dead MP outside who was running from Jenova. It doesn't really matter, anyways.
So I somewhat agreed with D on this, but I think the soldier tried to open the cell door while fully alive, and then was killed right after.
