The thought that they're SOLDIER crosses through Zack's mind as he's also handed a sword, the feel of it all off. They could easily force their way around him, slip past the curtain and head straight on out of here, regardless of the prop swords and how off balance they feel.

But the entire idea of coming into this part of the Saucer was to avoid attention, not draw more of it. Making a run for it is going to draw attention to them, and so Zack sends a helpless look in Kunsel's direction even as he's forced to keep moving. Nothing to do about it, buddy. Just gotta do it. But even so...

"What's the play? We don't know the lines!"

...No really they don't this could be just a case of mistaken identity.
