You were another individual who was promised something from the terrible organization that was Weapon-X. Going into it you thought nothing of it, but once you were exposed to the true horrors of the organization and what they did to people for their own personal gain, you were sickened. You were finally able to escape to America with the rambunctious Wade Wilson when he lit the anti-oxygen chamber he was trapped in on fire.
