Fringe : Season 3 : Episode 2 : “The Box”
Back to Earth-1, and the Earth-2 operatives are up to their usual havoc-causing antics. This time, it’s some kind of ultrasonic weapon component contained within a box that nobody can resist opening. Could there possibly be some link to the Earth-2 superweapon?
It’s almost not worth mentioning anymore, but Walter is heating something with a Bunsen burner – a definite no-no in modern laboratories.
As other posters have pointed out, Olivia-2 firing a gun that close to Peter’s ears would probably have resulted in permanent hearing damage.
When Peter is attempting to deactivate the bomb/ultrasonic emitter, he uses some kind of multimeter to check the potential differences between various components. How this works when the wires (and most of the other components) are encased in some kind of non-conducting gel is a mystery.
Where did that last subway train come from? The track electricity should have been turned off to allow Peter to get to the device, an alert should have gone out to all cars currently on the system and the train should have stopped at the station anyway.
