[Tony can't deny what Zack says is sound. They might be able to escape and they might even be able to change things back in their own worlds when all of this is over, but there is no guarantee that they can. And whatever has happened before they came probably still applies. If Zack lost a fight or was stuck with some unfortunately turn of luck before he got picked up in Norfinbury, then returning him home would return him right back to the conditions he left.]
