In terms of scientific validity, the latest episode of Fringe--’What Lies Below’--may be a stretch, but it does still retain the tension and mystery that is typical of a Fringe episode.

The Virus Before Time

Although the symptoms of the virus is reminiscent of rabies and similar viral diseases, Walter’s sudden extrapolation of a possible explanation for its dormant state seems like a stretch to me.  Indeed, it is not all the scientific flair around him that gives him the ultimate solution, but a simple conversation with Astrid that saves the day.  Not that I have a problem with this tactic, but the episode keeps up the tension only to climax on something as mundane as horseradish.

I would categorize ‘What Lies Below’ as one of the lesser science fiction-esque episodes of the show.  For a theory that cannot be tested in a lab, viewers will have to have faith on Walter’s assertions.

Olivia and Peter

Thanks to a hefty amount of insinuation that’s been underlying season 2, the sexual tension between Olivia and Peter is at an all time high.  Suddenly, every gaze becomes a subtle sign of yearning, not to mention the rather stimulating fight between Olivia and Peter.

What’s interesting is that it is not entirely clear why the pair do not come out with their feelings.  Perhaps it is professional courtesy; perhaps it is the nature of their insecurities, but it’s difficult to tell at this point.  What works for me is that neither character have a definitive obstacle, so viewers can never tell when these feelings might rush out.

‘What Lies Below’ is yet another entertaining episode from Fringe.  Given its lack of every overarching element that Fringe is famous for, the episode has successfully continued its subtle development of characters whilst tackling another near-death situation.
