The doctor shrugs as he watches the other men pat everyone down. "Contraband, apparently. We are looking for contraband. Not much is actually banned in Red Brick, though..."

The guard announces, "Yeah, we got some explosives and stuff here. Let me guess, you don't know who slipped these grenades into your pockets? Gonna have to log that...You can keep it, for now, but make sure nothing gets exploded while you're in the city, or you will all be arrested as suspects, understand?"
The guards seem to be sternly annoyed at the exiles' highly destructive weaponry...until one of the guards starts admiring the rifles.
"Man, these are some fine cannons you got here! No wonder you guys managed to kill some black necks!"

Eventually, the guards finish their search.
"You guys are clear, no signs of black neck tattoos or suspicious abnormalities..."
Tariq figures out that the whole "pat-down" routine is mostly a cover for checking people for raider tattoos. So what's the deal with the medical examination?

The doctor stands up, "Guess that means I'm up. Who wants to get examined first?"
