As Ko Sharmus prepared to sacrifice himself to detonate the death particle to stop the Master and his army, the Thirteenth Doctor fled into this nearby TARDIS and escaped the planet before the explosion destroyed all organic life. The Doctor flew the TARDIS back to the refugee planet where she had parked her own with this TARDIS's chameleon circuit causing it to assume the form of a tree. The Doctor complimented the TARDIS' chameleon circuit before abandoning it, stating that she could think of worse places to spend eternity. (TV: The Timeless Children)
Behind the scenes
- This TARDIS' interior, along with the other, used the same design as that seen in Fugitive Doctor's TARDIS earlier this season, rather than a model more closely based on the First Doctor's, as previous BBC Wales stories had done for "classic" TARDISes.
