YAY! Alright, goes abit like this.
Zack and Cloud are in the pods. Back and forth they would scratch things on the pods interior, sending messages back in forth. I believe they went like this
C: we need to get out of here
Z:at feeding time.thats the best chance.
or something fairly similar.One day, a man in blue(a turk,perhaps,by the suit) comes with their food.He opens Zacks pod, and zack punches the man.Zack then goes and opens Clouds pod,retrives his weapon,and carrys Zack from town.After this,its not really sure what happened.We know Cloud is unable to fend for himself,so Zack drags him.They catch a ride with a man heading in the direction they want.They ride i nthe back of the truck.
i hope thats what you were looking for.
