Oh, this looks interesting. Beyond The Doctor...in this instance what did Romanna do next.

It will not be available until Febuary 2021, that is going to seem a lot further away as time moves at a strange rate in these baffling times. Which coincidently is what I was thinking of changing this place's name to; The Baffling Times....
