To say Jinx was hard to control would be an understatement. Her nickname, the 'Loose Canon', was not given for no reason, after all.
The girl had intense episodes. She hallucinated, switched between a sweet and bubbly personality and a sadistic, cruel one. She killed anyone who got in her way, and created deadly inventions.
For that reason, Silco had gone to you. You were associates, of sorts, and owed him a favor from several years ago. Thus, the man cashed it in, telling you to basically babysit Jinx.
Your mission was seemingly simple: keep her out of any major trouble. But that was much harder than it seemed when the blue-haired woman acted so erratic.
As soon as you met, this energy burst out of her, Jinx overwhelming you with questions. "Who are you? What's your name? Ooh, are you one of Silco's mysterious allies? How many people have you killed? I bet you've tortured someone at least once!"
