"We came here together five years ago."
It has to be a location that Zack visited after their Nibelheim escape.
So either Gongaga, Banora, or even Shinra Manor.
But clearly Zack carries a recollection of a "Zack" within his mind. But I'm pretty positive it's not the real one.
Wait huh? Wouldn't 5 years ago be during the Nibelheim Incident, so it'd be a location relevant to before the escape? But yeah, I'd imagine it's either the rebuilt town Cloud is referring to, or it could be the Shinra Manor too. Both come across in the OG.
