Walternate 

The alternate universe, Secretary of Defense version of Walter Bishop deemed "Walternate". In the winter of 1985, his son Peter was kidnapped by our universe's Walter. Six months later, he ruined his marriage by obsessively trying to find Peter. In the interval 24 years, he became the Secretary of Defense, built mercury-blooded shapeshifters to ingratiate into our universe's society and found pieces of an ancient machine that destroys universes.

In 2010, he made contact with Peter and tried to convince him to use the machine (since according to an equally ancient drawing, the machine is attuned to Peter), but due to a budding relationship with Olivia Dunham (an FBI agent), he refused. Walternate then kidnapped Olivia and replaced her with her double, Fauxlivia. Peter, thinking that Fauxlivia was Olivia, started sleeping with her.

Fauxlivia was revealed to be an impostor, and returned to the other universe with a piece of the machine previously unknown and pregnant to Peter. She had a son, Henry. Walternate used Henry's blood to activate the machine, but it was turned off on this side. Because of this, Peter used the machine to destroy the other universe.

In the year 2026, Walternate attempted revenge on this universe, and managed to kill Olivia, but was stopped by Peter. 2026 Peter traveled back in time to 2011 to stop himself from destroying the other universe, but was erased from time. Walternate's 2011 fate is unknown.
Walternate's turned on the machine.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
