A quick glance around, acting as if paralized in shock, Kevin takes notice of Jaque.
Turning his head back to the soldiers, Kevin inconspicuously tucks his weapon into the back of his belt, and waves his hands in front of him in panic.
Sleight of Hand: 16 + 8 = 24
"No fire, no fire!" - Kevin says shakily with a French accent to the soldiers.
Sometimes it helps to be thought of as an outsider...
"Frenchman, are you armed? I have no wish to be taken." - Kevin yells towards the soldiers in French, with a submissive tone. Hoping that the man in the diner does indeed speak more French than Kevin has heard (and that the soldiers don't), he again stands ready to dive for cover on any signal, wether from the Frenchman, or the soldiers.
Bluff (for the submissive Frenchman routine): 4 (arg!) + 9 = 13
