When Walter describes his health status after the encounter with the worm, he mentions his "white blood count" being "through the roof". In fact, a very high (through-the-roof) white blood count (above normal) would be a sign of infection. See more »


Dr. Walter Bishop: My name is Walter. The Number 5 bus hasn't stopped here for over two hours. Not that it matters. I used up all my bus fare to dial seven wrong numbers. I can't remember Peter's number. I know it's got three fives, a one, a zero, and two sevens... but for the life of me, I can't remember the correct sequence.

The weaker episodes invariably set the baseline
29 March 2015 | by (North America) – See all my reviews

In reviewing individual episodes of some excellent series I have noticed that the weaker episodes are useful for establishing a baseline.

And this is one of the weakest in the series, especially disappointing after the buildup to parallel dimensions from the last season.

It is OK and fine to allow character buildup.

But what the writers overlooked at the is that the viewer watches with a constant vigilance (if you will) for non-logical events or paradoxes. If you introduce these, you lose the viewer.

In this story, Peter is going all James Bond with no gun or backup. He does this several times, finally getting captured and tortured for his trouble.

Didn't make sense to me when I was watching and does not make sense while writing about it.
