HBO Max Scores Exclusive ‘Doctor Who’ Streaming RightsJo Tro Do Plo Plo No: ‘Doctor Who’ Welcomes Back Familiar Monster Stay on target Ahh, Christmas. A time for family and friends to gather, exchange gifts, share a meal, and hide behind the couch during the annual Doctor Who holiday special.Still more than 230 days away, the Yuletide is already on Whovians’ minds, considering it marks the end of long-time boss Steven Moffat and Twelfth Doctor Peter Capaldi’s tenures.Capaldi has reportedly already filmed his regeneration scene—the one where he morphs into the Time Lord’s still-uncast 13th incarnation—but is set to complete shooting this summer.The rumor mill has been running since last month, when British tabloid The Mirror tipped the wibbly-wobbly, timey-wimey return of the First Doctor, played by David Bradley (reprising the role originated by William Hartnell).But good things come in pairs. And since we’re already expecting two Doctors and two Masters (though John Simm and Michelle Gomez are more likely to face off in the series finale, months before anyone trims their tree), should we hold our breath for two (or more) companions?Creators.co writer Lewis Jefferies on Tuesday hinted at the reappearance of Clara Oswald (Jenna Coleman)—killed, resurrected, and departed with a stolen TARDIS at the end of season nine.Now traveling through all of space and time, presumably with the immortal Ashildr (Maisie Williams), you’d hope Clara could stop by for one final goodbye.Social media has been buzzing with theories: Twitter users claim Eddie’s Diner (in Mermaid Quay, Cardiff, Wales) has been booked for two days of filming in July. The real-life restaurant, as seen in a number of Doctor Who episodes, is believed to be Clara and Ashildr’s TARDIS in disguise. You do the math.It’s not uncommon for the Doctor to meet and travel with a new companion each Christmas. Only three episode into his adventures with newcomer Bill Potts, it remains unclear whether the Twelfth Doctor will see her off on Dec. 25, or if fate has something else in store for the inquisitive lunch lady.While none of the reported parties—Coleman, Williams, Bradley—or the BBC have given official confirmation, this does sound like a great way for Moffat to tie up loose ends before handing Doctor Who off to showrunner-in-wait Chris Chibnall.Stream all of Doctor Who now for free with your Amazon Prime membership.
