With a nice touch of foreshadowing in Implosion, MacPherson (Roger Rees) had told Artie (Saul Rubinek) that he found Myka (Joanne Kelly) and Pete (Eddie McClintock) so raw, untrained and corruptible. This, unfortunately, proved prophetic.

This week we found Myka and Pete on opposite ends of the planet, with Myka in Berlin and Pete in Montreal, both following leads to locate MacPherson. While Myka turned up empty-handed, Pete hit the bulls-eye. In what should have been an easy snag-him and bag-him retrieval of MacPherson, Pete found the tables turned on him as MacPherson simply pulled out a set of tiny cymbals and clanged them together. The shockwave killed everyone within hearing distance. It was simply good luck that Pete managed to cover his ears in time. And with that first warning shot, MacPherson quickly engaged Myka and Pete in a lethal game of cat-and-mouse.

With nary a moment to lose, Myka was immediately summoned home to aid her ailing father (deftly played by Michael Hogan). Miraculously, her father was fine by the time she arrived. However, it was but a momentary recovery for he was soon felled by another mysterious attack. Fortunately, Pete had rushed to be with Myka and her family, and right away he and Myka uncovered what they thought was the source of Myka's father's illness: a handwritten, leather-bound notebook.

And the plot only began to thicken as Claudia (Allison Scagliotti) arrived with a purple goo containment jar and they discovered that submerging the notebook win the neutralizer as ineffective. With a quick call to Artie, they found out that the notebook was but one half of a deadly duo. It was Edgar Allen Poe's notebook and writing quill that, when used together, made the written word come to life. The person controlling the pen could write whatever they desired on a piece of paper and it came true. The notebook simply fueled the power behind the pen and recorded its evil doings. But Myka's father was succumbing under the weight of such a burden as his body had begun to absorb all those wrongdoings and he could not handle it. So Myka was entrusted with reading to her father to keep his mind occupied and firmly rooted in reality while Pete and Claudia went in search of the elusive feathered Poe Pen at a university in Portland. Identifying the person who had absconded with the pen was not very hard and, after rescuing a professor entombed in his own library and a near brush with death at the end of a falling pendulum, Pete and Claudia snagged the Poe Pen and rushed it back to Myka and her father.

One would have thought that would be the end of it as the pen and notebook had been secured and sealed in a protective purple pouch neutralizing their poisonous power.

But that is when things began to get really interesting: MacPherson was lying in wait just bidding his time to spring the trap upon them. It was only once Myka and Pete had both the pen and the notebook that MacPherson revealed himself. Holding Jack the Ripper's Lantern over Myka's parents and threatening to extinguish their lives forever, Pete and Myka finally realized this had been his nefarious plan all along. He had manipulated them into doing his dirty work for him and now he wanted the fruits of their labors. He wanted the Edgar Allen Poe Pen and Notebook.

Faced with the dilemma of whether to sacrifice Myka's parents or hand over the artifacts, Myka and Pete did the only thing they could do -- they gave MacPherson what he wanted. It was a harrowing lesson: MacPherson will do anything to get what he wants. Now it is up to Artie, Pete and Myka to figure out if they can afford to keep bowing to MacPherson's blatant extortion. Will they continue to be puppets on puppet-strings kowtowing to MacPherson's every whim?

What Worked

It was a touching display of support when Pete rushed to Myka's side when they thought her father was dying. To have him walk of the kitchen eating a plateful of food was unexpected, funny and surprisingly touching. It adds another fine layer to the complexities of Pete and Myka's growing affection for each other.

Also, quite fun was watching Myka's mother ask Pete if he had left some gloves in the kitchen and she handed over the purple gloves he used for handling the artifacts. Pete's chagrined grimace and off-the-cuff explanation that he used them for collecting evidence was just hysterical.

While the artifacts themselves seemed innocuous enough, their power was certainly impressive to behold. First, watching the words literally infect Myka's father as he read the notebook was alternatively fascinating and revolting. Then seeing the power of the pen as each word it wrote came true, such as the fire in the locker, the professor sucked into the library wall, and the giant swinging pendulum, was just astounding. The crowning, if not somewhat predictable moment, was watching Bobby hand Tamara the poem that contained only one word: "mine." It takes only one word to destroy a person's free-will. Astoundingly, Bobby was absolutely correct when he said, "words have power." It was just horrifying to see which words he chose and how he used them.

What Didn't Work

While it is amusing to watch Mrs. Frederics (CCH Pounder) pop in and out unexpectedly and to watch Artie do a double-take each and every time, it felt a bit overworked in this episode. Surely, Mrs. Frederics has more to do with her time than to check up on Artie every time he chases after MacPherson.
