Really hope someone can help with this as it's bugging me to death.
In one specific episode (no idea which season, sorry), either a captured enemy or a person of interest who I think was an arms dealer is brought in to CTU headquarters for questioning.
Typically Jack is impatient, and this quickly turns in to a bizarre torture scene (although I can't remember how) where the guy ends up dead on the floor of CTU, leading Jack using a couple of power cables to jump start the guy back to life. The power cables part is what I seem to remember the most.
I know that's a really sketchy outline of the plot, but I can barely remember it. If this sparks memory in anyone, can you tell me who this 'arms dealer' was that Jack was torturing?
