Take the cigarette and thank him
From Create Your Own Story
You gladly accept the cigarette and give your thanks. Then the RED spy takes a knife to your throat and forces you up against a wall.
THe cut is only minor, not drawing deep enough to slit your throat but you are still in danger as the RED spy studies you maliciously.
"I knew you were a spy, mon ami, and I have to say, you almost 'ad me fooled."
You don't say anything.
"But I know why you are 'ere...for ze sniper, non?
"Oui" You see no point in lying to a fellow spy who has all ready foiled your engineer ruse.
"I will strike with you a deal, mon ami." He lets you absorb this for a second.
"I can go right now and sound ze alarm. Mon comrades can come and gut you for being a spy. Mais, if you can promise me something...I will let you go. Do we have a deal?"
