Central to the case is Dr. Bilac who seems to have some connection to what is happening. As the FBI agents continue their investigation - a profusion of rats in the museum is only one of the things they have to put up with - the State Department in Washington is considering whether to return of relics.

Did You Know?


Originally the script called for hordes of common house cats to attack Mulder and Scully. Unfortunately, the cats refused to attack under direction and did pretty much nothing. All felines, from little kitten to big tigers, are absolutely lazy when having well fed and not in danger. See more »

Cats and Rats
7 July 2006 | by See all my reviews

After watching Pusher, arguably the best episode of season three, the viewer is then thrust upon Teso Dos Bichos, a poor excuse for an x-files episode. It's easily the worst episode of season three and quite possibly the entire series. First of all, the title is Portuguese, yet the episode begins in Ecuador, where Spanish is spoken. The episode starts off on the wrong foot with the teaser. First, there is snow at the dig site. Then, everything is dry. Minutes later, there is snow on the ground and it is snowing heavily. Bad continuity error. The guest acting is bad, starting with Dr. Roosevelt, continuing to Dr. Bilac, and finishing with Mona. The story is convoluted and confusing. Is the killer a jaguar spirit, Dr. Bilac, a bunch of cats, or rats? Are the killings related to the curse, or is it just sewer cats on the rampage? Mulder and Scully are in the sewers trying to find Dr. Bilac and they show a shot of a bunch of cats, seemingly calm. If they are killer cats, why are they so calm? Did the jaguar spirit transform into several cats? The story is too disjointed to make any logical sense. The music in some parts is quite interesting and there is some good Mulder/Scully dialogue which is what allows this episode to have a couple of points. This is John Shiban at his worst. Luckily, Jose Chung's "From Outer Space" is coming up shortly, so the pain from watching this episode won't last too long.
