I'm still hazy on this part, DSW.

[quote]During their last mission, Billy and Slade were caught in Shanghai and tortured for 6 months to give up information;water boarding was the most often used. Billy broke, betraying Slade and ASIS. The two fought and Slade killed Billy at a cost-his right eye. [/quote]

If they were being tortured, how did they end up fighting? They would have been restrained and under guard, I imagine, unless their captors were incompetent. So how did they both get loose and start fighting?
