This one feels the most important to the Doctor's future, considering that the opening and closing scenes follow two companions who had their memories wiped like the Doctor. I can see the emotional throughline where Zoe speaks of the cruelty of memory wiping flowing into Donna's situation, and the hint that Jamie and Zoe may get to keep their returned memories perhaps suggests an optimistic end for Donna too.

Frazer Hines and Wendy Padbury are a delight, and effortlessly slip back into their roles. Frazer Hines, in particular, is excellent, with a somehow even more convincing Scottish accent than when he was in the show.

The story itself, The Mind Robber, is a wonderfully unique affair. I admire the fantastical edge of this void where fictional creations such as Gulliver and Rapunzel can meet, and the TARDIS's collapse is a stunning visual. Jamie doesn't get a ton to do, which admittedly is partly due to Frazer Hines' illness at the time of recording, but they at least find a creative solution for Jamie's brief recast, with the Doctor getting his face wrong during the facial puzzle.
