* The message's use of "sword" as a hint to the space-hearse's location seems like ArtisticLicenseAstronomy, considering that the constellation Orion only ''looks'' like a man with a sword from the perspective of Earth's solar system, and only to humanoids who carry swords at their waists for that matter. However, Orion ''must'' be a well-known configuration in the Whoniverse, because the "Eye of Orion" was cited many times in the Classic series as a universally-famous beauty spot and tourist trap! So whether the constellation is interpreted as a sword-bearer by the inhabitants of worlds directly opposite from Orion in Earth's sky, with our own Sun as yet another star in the figure's weapon, or whether it's an idea that got passed around by Ice Warriors and/or AncientAstronauts like the Osirans who used to hang out on Earth, the notion of Orion isn't confined to just the local humans.

* FridgeLogic. The Diagnostics on the door locks tests every few seconds, but stop at night, part of the base going into a lower energy state to help maintain sleep cycles. So the very time when everybody is asleep and unable to react is the exact time when the base's integrity isn't being checked!
** Although that ''could'' make sense, if the current technology is so reliable that human error or malfeasance is to blame for any failures that still occur.
