The Tsuranga Conundrum was the fifth episode in the eleventh series of Doctor Who produced by BBC Wales.

Synopsis

As the Thirteenth Doctor and her friends end up stranded without the TARDIS on a hospital ship in space, with a strange and potentially deadly intruder on board, it is up to them, the crew, and the patients to figure out what it is, what it wants, and how to stop it before the creature tears the ship apart.

Plot

On Seffilun 27 in a Junk galaxy, the Thirteenth Doctor, Ryan, Yasmin, and Graham are hunting for something the Doctor desires to find with special detectors retrieved from the TARDIS parked nearby. While looking, they find something, the Doctor realising that it is a sonic mine, and accidentally triggers it and explodes just as the Yaz asks how long they have

The Doctor awakes on a hospital ship Tsuranga, finding the others alright despite her own apparent pain in her side.

References

The Doctor

• The Doctor claims she is a doctor of medicine, science, engineering, candy floss, LEGO, philosophy, music, problems, people and hope, but mostly hope.

Culture

• Graham mentions how he has watched every episode of Call the Midwife, although he looks away at the squeamish parts.

Species

• Gifftan males and females can become pregnant, with males only birthing male children and vice-versa. Gifftan young are gestated for a week in a pregnancy sac before the sac is painlessly cut open during birth.
• Gifftan babies are born with two umbilical cords.
• Images of a Cyberman, an Ood, a Weeping Angel, a Raxacoricofallapatorian, a Sontaran, a Silent, a Silurian, and a Zygon appear on a console screen in rapid succession before Mabli selects a briefing on the Pting.
• Time Lords possess an organ called an exo-spleen. When damaged they could cause pain.

Technology

• Anti-matter drives were used in the 67th century to power their ships.

Sport

• Yaz mentions footballer Siobhan Chamberlain when kicking the Pting down a corridor on the Tsuranga.

Story notes

• Pretty much every scientific fact about anti-matter given by the Doctor in this episode is true to real science. However, in reality, because antimatter is produced via pair production, energy gained by antimatter-matter reactions would not exceed the energy required to create it; therefore energy generation would have to be performed by captured antimatter that has not been manufactured.
• Tim Price receives a creator credit for the Pting, the first time such a credit is given on a creature or character's first appearance.
