Patrick took the guns and bullet with silent nod. Achilles only looked like this when things were about to get very serious and very deadly. He moved back behind the bar, checking over the gun in his hands, taking these few precious moments to familiarize himself with the weapon. He stored the extra bullet in one of his front vest pockets where he could get to it easily. He moved his head back up over the bar. 

"Achilles, be careful. Don't you dare go getting hurt on me." Achilles was standing in front of the argumentative civilian, attempting to protect him of course. Patrick hadn't paid too much attention to the man, he had been distracted by the strange sounds he had been hearing coming from outside the bar. He had never even seen a Vertibird from a distance let alone heard one before, so despite hearing its approach before the others seemed to have heard it, he was too confused to let out any sort of warning. He took some deep breathes to calm himself as the Enclave soldiers approached.
