Polite Dissent

Does Godwin’s Law apply to television shows? Actually, though the science was questionable, I thought the storyline was sufficiently creepy to be a good episode overall.

The Plot: At a wedding, the groom’s grandmother notices someone standing in the back who alarms her. As she moves to confront him, she starts gasping for breath, turns an ashen gray, and then collapses, dead. Soon, other members of her family start dying as well – fourteen total – and the Fringe team is called in. After examining the corpses, Walter and Peter declare that everyone has died of asphyxia (suffocation). Agent Dunham notices a tattoo on the grandmother’s arm that indicates she was a concentration camp survivor. Poking around the church, they find the groom, still alive, but gasping for air. He dies at their feet, bringing the death toll to fifteen.

At the lab, Walter starts his autopsy of one of the victims and notices that the blood is a deep blue (Prussian blue, perhaps?), indicating some form of toxin exposure. The team also realizes that everyone who died was a blood relative and a direct descendant of the grandmother. Re-examining the church, Peter finds a candle that is different from the others and brings it to Walter. A quick run through the lab equipment shows that the candle contains some sort of cyanide compound. Walter suspects the deaths at the wedding were an experiment by the murderer to see if his toxin would work, and predicts that he will strike again soon. Sure enough, in a similar episode, nine people die in a coffee shop. The connection this time is that they all have brown eyes.

Back at the lab, Walter has isolated the toxin and shows how it can be set up to target different proteins, depending on who the murderer wants to kill. He points out a carbon chain on the toxin that he claims in the creator’s “signature.” When Peter remarks that it looks like a seahorse, Walter realizes that the poison was created by his own father who had been a scientist in Berlin until fleeing in 1943 (his nickname was “seahorse”). He has kept his father’s formulas in some old German books, Peter sold them ten years ago when Walter was in the asylum. It all turns out to be a red herring though, as they are not connected to the mysterious murderer.

Meanwhile, Walter has managed to get a partial DNA profile of the killer from skin cells left on a fingerprint. He claims that it’s a bad sample though, because the telomeres are severely damaged, suggesting that the person must be at least one hundred years old. The FBI is able to track down the chemicals used in the making of the toxin, and get the killer’s address. They search the house (poorly), but find nothing, as their target is at that very moment escaping from his lab in the basement. Eventually, Agent Dunham finds the basement lab, but the killer has set a trap for them, with some of the toxin specifically targeted to Walter. Luckily, Dunham and Peter get Walter to medical care in time, and he survives. A clue (found by Dunham even) tells the team that the killer has his sights set on a World Tolerance conference going on in Boston. Peter, Dunham, and the FBI head over to the conference to look for the killer. Walter stays behind, mixing up something in the lab, and then he heads over to the conference himself. Peters spots the poison and he and Dunham are able to confiscate it before it can be activated – but they are interrupted by a horrible coughing sound and rush over to find the killer, disguised as a waiter, gasping for breath and dying. Walter has turned the tables on him and made a version of the poison specifically tuned to his DNA. As the episode ends, Peter and Walter are still puzzled how the murderer got his hands on Walter’s father’s research, not realizing that the killer was a Nazi scientist himself, somehow still alive sixty years later.

1. Stay on Target
According to Walter, the toxin binds to a particular protein, and this protein can be altered depending on who the target. Unfortunately, the Nazi scientist’s poor understanding of molecular biology has doomed more people than he realizes. For instance, there is no protein specific to brown eyes. Brown eyes simply have more melanin than other eye colors — but the other eye colors still contain melanin. Everyone in that coffee shop, including the Nazi, should have died. Similarly, there is no special protein in dark skin that sets them apart — people with darker skin simply have more melanin than lighter skinned people. Trying to kill off the darker skinned people would have killed everyone — well, except the albinos. Good job, Nazi scientist. Now the albinos rule the world.
Suddenly, in a virtual deus ex machina, the toxin can be programmed with a specific DNA — even though Walter made it point, repeatedly, to mention that it was created before DNA was understood.
Even if the poison could target DNA, how are you going to get that big of a molecule into the nucleus of the cell, let alone through the cell membrane?

2. Those Who Do Not Know History…
Walter is off on his history: the discovery of DNA predated the Nazis, not the other way around. DNA was discovered in the middle of the 19th century, well before the Third Reich. By the 1920s, there was strong evidence that DNA was involved in inheritance, with the first definitive experiment performed in 1943. Walter is probably thinking of Watson and Crick’s famous work on the structure of DNA, which was published in 1953.

3. Sure Hope He Never Testifies in Court
The signs Walter mentions — petechiae, bulging eyes — are seen in asphyxia caused by strangulation (they are related to increased venous pressure in the head from the compression of the blood vessels in the neck), not by asphyxia due to toxin inhalation.
Can the vitreous humor, a gel-like liquid, really swell?

4. How Dare You Kill People With My Dad’s Poison!
Walter was upset that the murderer was “perverting” his father’s work, but let’s not forget that his father’s work was a nasty chemical warfare agent.

5. It Is Impolite To Inquire As To A Telomere’s Age
Telomeres are special DNA sequences on the ends of chromosomes that keep it from breaking down or fraying. There has been some good research suggesting a link between aging and the break down of telomeres. Still, it’s a dubious stretch to tell someone’s age from looking at their telomeres.

6. Nasty Poison
Hydrogen cyanide can kill remarkably fast, depending on its concentration.

6. Comes With A Certificate of Authenticity
That seahorse “signature” is so incredibly bulky and large that it would interfere with the biological activity of the toxin. Plus, it’s bad planning because it provides an easy target to identify and develop an antibody against.

7. Two Puffs Four Times A Day
A nit-pick here, but the groom sure has poor inhaler technique (but then, so do many of my patients — and a quick Google search reveals that much of the internet has a similarly poor understanding.) The inhaler should be held an inch or two in front of the mouth, not actually in the mouth.

The science was quite questionable this week, but I thought the story did a good job keeping the suspense going — and the Nazi scientist was truly creepy — so it’s a wash and the Doomsday Clock stays at 11:58.
