Deny the deal and suffer the consequences
From Create Your Own Story
You think about this for a second..."I say to your proposition...non." Without hesitation the spy reaches over to the opposite wall and sounds the alarm. In seconds 2 HWG's, a scout, a Pyro and a Demoman all come from within the RED fort. You are immedeatly subject to several forms of torture including scaldings, beatings and eventually disembowelment.
When all of the torture is done you are still barely alive. Just long enough to see your team's attack fail miserably.
