Since current Doctor Who showrunner Steve Moffat is also leaving after season 10, the future of current companion Bill (Pearl Mackie) is also uncertain.
As the current season of Doctor Who carries on, fans are still speculating as to what Peter Capaldi’s last excursion as The Doctor will entail, over the episodes that remain.
But does any of that apply to what/who is in the vault on Doctor Who this season?
[SPOILERS for those not caught up on Doctor Who ahead.]
