When the Thirteenth Doctor regenerated at the end of Power of the Doctor and everyone was surprised to see a familiar face, theories spread like wildfire. Mine—and the one that felt like a glimmer of hope in my fan heart—was that, if they were going in that direction, they might as well make the 60th anniversary a celebration of the Doctor’s different incarnations. That did not happen, and that is not such a bad thing. But what I had genuinely hoped for was this: that the Doctor’s regeneration, this time, would be “broken”, that old faces would return at random, beyond his control, and that Ncuti Gatwa’s arrival would mark a rebalancing of the regenerations. Well, thankfully, Big Finish was there!
