This may be the best episode of the season so far and one of the best of the series. It looked straight-up with the man's vanishing but then came Jack's capture and torture. I'm amazed they got so graphic with it, especially the holes in his hands. I also liked how he kept trying to be in control, trying to talk to this unbalanced woman and not let his obvious fear out.
The actual story was also great with the twist of the guy being a con artist and the added twist of his partner being his mother. And then the last great one as the guy turned out to be conning her. I loved how her face showed more pride than shock, as if happy he'd learned so well. Having Jack keep her secret was a nice touch that capped off a real nail-biter (no pun intended) of an ep.
