The series 12 finale of Doctor Who back in March ended on a cliffhanger, with Jodie Whittaker's Thirteenth Doctor imprisoned and her loyal companions (or "fam") back on Earth without her. Fortunately, we don't have much longer to wait to find out what happens. The BBC dropped the official trailer for the upcoming holiday special, Revolution of the Daleks , slated to air on New Year's Day.

(Spoilers for S12 below.)

As I noted in my review earlier this year, series 12 felt like classic Doctor Who , to the delight of longtime fans disappointed by Whittaker's first outing. (I thought that first outing was solid and showed a lot of promise.) In the episode "Fugitive of the Judoon," the Doctor encountered the intergalactic police force-for-hire, the Judoon (introduced in the series three episode " Smith and Jones "). The Judoon were supposedly hunting a man who lived in Gloucester with his wife, Ruth (Jo Martin). But their true target turned out to be Ruth, who recovered lost memories and declared herself to be the Doctor, with her own buried blue police box TARDIS. Yet neither Doctor had any recollection of the other.
