Story notes

 * This story introduced the new version of the Time Vortex as well as giving us a more in-depth look at it.
 * While the Doctor says in this episode she's never had a flat before, previous stories including PROSE: Verdigris and PROSE: Endgame indicate otherwise.
 * The plot of the episode takes inspiration from the films Ice Spiders and Eight Legged Freaks. This is due to using both the themes of scientific blunders from the former and toxic waste mutating normal sized spiders from the latter.
 * Almost every science fiction fact about spiders mentioned or done in the episode has its ground in real world science.
 * Internationally renowned zoologist and conservationist Dr Niall Doran was consulted for this episode.
