Long story short? Zack broke one of the game machines by accident, and then we both made a bunch of poor choices that ended with security chasing us around the Gold Saucer and Zack punching one of the actors in a play. To be fair, we were both pretty young back then. Teenage boys aren't necessarily known for being the brightest. Add SOLDIER strength to that, and well...

[He shrugs, though she can't see it. She can probably picture how that might go.]

The Gold Saucer wasn't happy with us, and neither was Zack's mentor, Angeal.
