Time Lords

Time Lords have two hearts and three brain stems.
One stipulation of the Fatality Index is that a death sentence of a Time Lord must be carried out by another Time Lord. That Time Lord must also swear an oath to guard the condemned's body for 1000 years in case of relapses.
The Doctor worries that, because he managed to temporarily "borrow" eyesight from his future self, his future regenerations might all be blind, or he might not regenerate at all.

People

Pope Benedict IX made a personal recommendation for the Doctor in 1045. He remembers Pope Benedict, and recalls, "I knew she was trouble, but she wove a spell with her castanets."
The Pope pays the Doctor a visit in the lecture hall.
The Pope is also known as the Bishop of Rome.
The virtual Doctor says that the Pope doesn't "zoom around in the Popemobile, surprising people".
An Italian newspaper brought a minor story known as "Colossal-Lotto" about a lottery winner by the name Harrison O'Shea in Milan written by Paolo Ferrera.
Virtual Bill brings Penny home on a date. Penny runs away after seeing the Pope in Bill's bedroom.
Virtual Bill thought that virtual Moira would be out with "Harry" tonight, who is actually named Howard.
The last emails sent before the translator kills himself were, chronologically, to Abramo Tognaccini (We have been tricked by the devil – in French), Daryn Mcloughlan (Pray for your family), Phil Bond (Pray for us all tonight), Franco Esposito (The world is not what we think – in French), Christina Tom (Farewell), Kevein Paters (Chapel Day), Albertina Ricci (Pray for us all – in French), Bill Pullman (Thursdays meeting), Peter Dukes (The devil's work has been done), Nicia Russo (We have been tricked), Michael Finch (Missed meeting), Stefan Anchorage (Farwell on this earth – in French), and, finally, four hours before death, to CERN European Organization for Nuclear Research, VERITAS, containing the translated text.
The President is lying dead in the Oval Office. News reports say he hasn't been seen for 12 hours.

Technology

The Doctor gets an email on his sonic sunglasses, which the virtual Doctor has sent, from within the Shadow World simulation.
The Doctor also uses his sonic sunglasses to scan people's data, as he cannot see them.
- Data the Doctor can detect are:
  - Gender (male and female)
  - Age (in years)
  - Height (in centimetres)
  - Weight (in pounds)
  - Heart rate (in BPM)
  - Temperature (in degrees Celsius)
- He can also get a sense of the architecture around him, again using the sonic sunglasses as visual aid.
The Doctor employs a reading aid with circular Gallifreyan script on it, which he hopes will temporarily restore his sight. He confirms that it's deadly.
Bill notes that the Haereticum has WiFi, and the Doctor says of course it does; it's a library.
According to a plaque at CERN, its Large Hadron Collider, which was first tested on 10 September 2008, is the world's largest and most powerful particle accelerator. It has a diameter of 27 kilometres, and, to work, requires the magnets to be cooled at -271.3°C—a temperature colder than outer space. To achieve this, much of the accelerator is connected to a distribution system of liquid helium, to cool the magnets, as well as to other supply services.
The translator has a computer.
- He E-mails the translation to CERN.
The CERN employees all have TNT explosives wired under the canteen tables.
The countdown to destruction at CERN happens on a flatscreen TV.

A flatscreen is seen in the White House.

Organisations

CERN is the largest particle physics laboratory on the planet.
The Pentagon is the headquarters of the United States Department of Defense, located in Arlington County, Virginia.

Religion

An early Christian sect managed to translate the Veritas before all commiting suicide.
The Veritas is older than the Catholic Church itself.
Suicide is understood to be a mortal sin in Catholicism, leading one to hell.
Pope Benedict said that the Doctor was "more in need of confession than any man breathing", but when the offer was made, the Doctor replied "it would take too much time".
The Doctor says that religion is "designed to confuse the uninitiated", as Angelo says of the layout of the Haereticum.

Food and beverages

The man in the cage had been there a long time and eaten lots of food, bananas and sandwiches included. He also had coffee.
The CERN employees all drank all sorts of wines before the end. Chateau Cissac included.

Locations

A long time ago Nardole told the Doctor that he followed him from Darillium and that he has full permission from River Song to kick his arse.
Nardole tells Bill that the Vatican is in Rome, which is in Italy.
The Haereticum contains a cage with the Veritas locked inside.
A total blackout has occurred at the White House. The Doctor confronts a Monk in the Oval Office.

Weapons

Piero has a gun that he uses to kill himself.

Culture

The Pope hopes for God to help the Doctor]] on his quest.
Virtual Bill exclaims "Harry Potter!" upon seeing the Haereticum for the first time.
Virtual Nardole says that the Doctor and Angelo would be "wizard" at writing Christmas crackers, when, together, they say, "Truth in the heart of heresy" / "And death in the heart of truth".
Virtual Nardole relates holographic simulations, with holographic people to the holodeck on Star Trek, "or a really posh VR without a headset".
Virtual Nardole compares the simulation to Grand Theft Auto, and the virtual Doctor likens the inhabitants of the Shadow Earth finding out they are a simulation and committing suicide as a result to a hypothetical scenario in which "Super Mario realises he's inside a video game".
The Doctor owns a snakes and ladders game in the TARDIS.
Upon seeing the Monks, the Doctor pokes fun at the saying that no one looks good in the morning.
Many of the simulated people took the Shadow Test to confirm they were not real.
