[AgentZero]

Agent Zero staggers to his feet, a vile stream of profanity spewing from his mouth. Even a fool should know that even all the Guiness in the world can't keep an Irishman down. However, smacking your head on a table when you slip on the stuff will do the trick nicely. Realizing he is soaked head to toe in Guiness, Agent Zero rolls his eyes strangely, activating a command in his retinal recognition software. The Guiness soaking his clothing sprays out in every direction, yet every drop manages to land in an empty glass belonging to the other patrons.

"That round's on me, lads!"

Agent Zero then notices the bill nailed to his shoe.

"Oh. I guess it is actually on me. Bugger."

Agent Zero strolls over to the bar, flicking through his credit cards until he finds his US Government Slush Fund card and hands it to Woundwort. In response to the newly-promoted General's query, AZ tells the barman to file the charge for 76 litres of Guiness under Entertainment/Jenna & Barbara. After payment is accepted, Agent Zero tucks the receipt away, then tips Deadstar generously for defining FBW.
As he turns to leave, he catches sight of David's new bodyguard, and stops in his tracks. The two stare at each other across the room, and the whole cantina grows silent. Agent Zero tilts his head to the left, then the right, cracking the vertebrae in his neck. David's bodyguard slowly cracks one knuckle after the other and unhooks her holster-guard. An electric charge runs through the cantina. The tension is unbareable. Soon the place will errupt into the most unprecedented level of violence any cantina has ever seen. Deadstar and Woundwort hastily begin filling out insurance forms, while the other patrons begin edging towards the windows.

Then, most unexpectedly, the two nod courteously to each other, and Agent Zero heads out the door in search of FBWs, and of course the meaning of Mac's cryptic reference to 'the O word'.
