The Sixth Doctor Solo

This section of the Sixth Doctor era opens with the Trial, in which Peri departs and Mel...well, Mel is introduced as a character, but the Doctor hasn’t met her yet. Although this was never shown on TV, Big Finish has established that the Doctor returned Mel to her proper place and time (sort of) and didn’t choose to meet her until later. This creates a large gap where the Doctor basically wanders around on his own, which he never did on TV. Big Finish seems to have been fond of this idea, with several stories in 2018 and 2019 featuring a solo Sixth Doctor. This also means that this Doctor’s last televised adventure takes place rather early in his “life,” as far as Big Finish is concerned. That gives them a lot of latitude to make changes, and add new companions and stories, which is frankly all to the better.
