Doctor Who Season 15 Must Explain Why Varada Sethu’s New Companion Looks Like Mundy Flynn
Happy Days Are Coming To The TARDIS With Sunday & Mundy
Assuming Varada Sethu returns in time of year 15 as a fresh character , Doctor Whocannot cross the obvious resemblance to Mundy Flynn under the narrative rug . Not only do the Doctor and Ruby both spend plenty of prison term with Mundy in " Boom , " the soldier ’s face remains on full display at all times . If the medico can forecast an object ’s precise weight merely by control Ruby shake off it into the airwave one fourth dimension , then he can recollect a soldier ’s boldness .
More significantly , only fiveepisodes ofDoctor Whoseason 14 are left , play along by a Christmas special , before season 15 presumably airs in 2025 . In all likeliness , therefore , only six episode will pass between the Doctor coming together Mundy Flynn and the Doctor get Varada Sethu ’s new lineament as his fellow traveler . Given this perilously short gap , ignoring the visual law of similarity between persona just is n’t an option . For neither the Doctor nor Ruby to get up their raw friend ’s obvious resemblance to the Anglican Marine they encountered on Kastarion 3 would be ridiculous .
Billie Piper ’s iconic Doctor Who character set the Browning automatic rifle for next fellow traveller , and Millie Gibson ’s Ruby Sunday share many similarities .

Doctor Whocould perhaps get by with snub the déjà vu if Sethu ’s two role met different Dr. . Karen Gillan , for exemplar , first come out - in large physical composition , it should be notice - during David Tennent ’s stint as the Tenth Doctor , then resurface as Amy Pond for Matt Smith ’s tenure . Gillian ’s two role appearing in different eras ofDoctor Whoreduced the need to explain why her Soothsayer look a bit like Amy Pond , but with Varada Sethu returning only six episode later and both of her characters meeting the same MD , season 15 wo n’t have that luxury .

Peter Capaldi ’s threefold part as the Twelfth Doctor and Caeciliusbecame a in full - fledged plot point , culminating in the Doctor realizing he had subconsciously choose Caecilius ’s form to remind himself of the lessons watch during that particular adventure .
WhileDoctor Whodid excuse Peter Capaldi play Caecilius and the Twelfth Doctor , it glossed over Capaldi ’s part as Frobisher inTorchwood . Steven Moffat at last revealed Frobisher as a descendant of Caecilius .
Doctor Whoseason 15 can , and should , continue in that mineral vein by providing an in - universe reason for Varada Sethu ’s riposte . take on the Doctor revert to type and recruits his next companion from present - day Earth , the most logical explanation would be making Sethu ’s time of year 15 companion character an ancient ancestor of Mundy Flynn . The Doctor and Ruby might even accept this stranger as an spare TARDIS passenger part because of her biological connexion to someone they already befriend in the past ( or , indeed , the future ) .
