Prior to this week's season finale of Intelligence on CBC, I half expect to hear: "Previously on Intelligence ... everything goes to hell."

The last episode, "Dante's Inferno," takes the threads of the previous 11 episodes, wraps them around the necks of Jimmy Reardon (Ian Tracey) and Mary Spalding (Klea Scott), and leaves us with a divine drama that somehow must be at least somewhat wrapped up this week, or leave us with a hell of a cliffhanger before we've heard about a second season.

Jimmy and Ronnie are too late to save Johnny, the Vietnamese tortured by Dante's men to reveal Reardon's connection to his nephew's death. Did he talk? What does Dante know? Hard to say. It's always hard to say with this show - who knows what.

Jimmy's furious with Mary for not instantly answering her phone while they were pursuing Dante's car, but she was busy shredding files rather than let them fall into the hands of her CSIS overlords, who are infiltrated by moles. Besides, Jimmy needs to save some rage for later, given how the episode ends. For now, he insists she preserve his anonymity in the murder investigation, which she does reluctantly.

Dick Royden, who Mary suspects is an American double agent, meets with Ted to coax from him his files and a statement on Mary's culpability in the death of their wireroom mole, Lee. Royden dangles Mary's old job as the carrot in front of Ted, and the threat of being the scapegoat himself as the stick.

Ted's DEA pal is still working with Reardon's American distributor to lure Reardon down to their jurisdiction. And the convergence of events in this episode make  the option of fleeing to another country appealing to Reardon. So things are looking good for Ted so far.

Things aren't looking quite so good for Mary. At the not-particularly-polite request of her senator friend's flunky, Mary is attempting to gather hard evidence to prove Royden is a double agent, with the help of Katarina's patriotic prostitution allowing her access to his incriminating cell phone activity (and allowing him access to her wallet - so now how much does he know?).
