Doctor Who: 10 Great Ideas That Went Absolutely Nowhere
6. Thirteen's Fob Watch
The finale of Flux saw the Thirteenth Doctor hide a fob watch containing her lost memories deep within the TARDIS.
This was a strange decision considering that her mission in this series was to uncover the truth about her past, but ok, fair enough. Showrunner Chris Chibnall was just saving the watch for a future story, right?
Well, no. Eve of the Daleks and Legend of the Sea Devils came and went without so much as a mention of it, and with the Thirteenth Doctor now having regenerated, it's unlikely that this plot thread will ever be revisited.
And that's highly frustrating, as well as being a shame. Think of the craziness that would ensue were the Doctor to dive into that watch's secrets - we could learn more about Gallifrey, the Division, and the Doctor's own history.
The watch could've even served as a way to revisit previous Doctors. Chibnall invented a mechanic (the Guardians of the Edge) to bring back classic Doctors in The Power of the Doctor, even though he already had a mechanic sitting right there.
At the very least, the watch could give us more memories of the Doctor's missions with Karvanista, and more screen time with that good doggo wouldn't go amiss.
