Theending ofDoctor Who ’s sixtieth - day of remembrance specialsshowed David Tennant ’s Fourteenth Doctor bi - generating , meaningFourteen stay as an autonomous being while Ncuti Gatwa ’s Fifteenth Doctor also enrol the disturbance . The moment was exciting , and now , has thankfully been essentially sustain to be a one - off happening .
Out ofevery actor to toy the Doctor , Ncuti Gatwa is the first to make his entrance as the show ’s wind actor without their precursor also being ejected from the cast . Fourteen helped Fifteen vote out the Toymaker beforeTennant ’s Doctor basically retired from the lifespan of a heroical Time Lordto subsist an ordinary life with the Nobles , while Fifteen keep his adventures through time and space .

Gatwa’s Fifteenth Doctor Hints That He Can’t Bi-Generate Again
Doctor Who’s bi-generation doesn’t sound like a pleasant experience
InDoctor Whoseason 14 , instalment 2 , " The Devil ’s Chord,“the Doctor narrate Ruby Sunday of the cost bi - generation took on him , and that the process was necessary to vote out the Toymaker . speak to Ruby , the Doctor say , " It tore my soul in one-half . I ca n’t last that again . “The message is clear : Even if the physician could bi - generate again , repeating the exploit would probably kill him .
Making bi - coevals a one - clock time issue restores a big part ofDoctor Who ’s formula . While the Dr. can die , the closest the character ever comes is regenerate .
Making bi - generation a one - time event restores a magnanimous part ofDoctor Who ’s rule . While the Doctor can drop dead , the end the quality ever come is regenerating . Regeneration is a process that a Time Lord undergoes to cheat destruction , but it results in a complete overhaul of their character and personality - with the result essentially being a brand - new individual with the accumulative memories of their harbinger . So regeneration carries with it sure stake , as it means a certain variant of the Doctor " dies " when they endure the cognitive operation . If bi - contemporaries remained as a Dr. Who mainstay , those stakes would n’t be present .

Doctor Who Having The Ability To Bi-Generate Again Wouldn’t Have Worked
Bi-generation means a departing actor has no reason to leave the show
Part of the reasonDoctor Whohas enjoy such a long footrace is that the show transforms every few seasonsor so . At the pith of that variety is the histrion playing the Doctor leaving the show when their interpretation of the type regenerates . The import has become something of an emotional authentication inDoctor Who , specially since the dealership ’s revival in 2005 . If bi - multiplication had remain a possibility for the Doctor hold out ahead , even if it did n’t happen every metre , viewers would always expect an doer to persist even after their time as the Doctor would traditionally terminate .
For object lesson , if Ncuti Gatwa ’s Fifteenth Doctor were to bi - generate at the remainder of the actor ’s running game on the show , there would then be two Doctors who would have no reason not to carry on saving the Galax urceolata .
For example , if Ncuti Gatwa ’s Fifteenth Doctor were to bi - beget at the end of the actor ’s run on the show , there would then be two Doctors who would have no reason not to carry on redeem the galaxy . This would then command writing a fresh excuse as to why the outgoing doer no longer appears as part of theDoctor Whocast going forward . finally , the explanations would become progressively more flimsy until they stopped being credible . Alternatively , Doctor Whowould need to permanently become a multi - Dr. story- which would bankrupt what ’s currently a special consequence reserved for specific milestone .

The latest Doctor Who series introduces the Fifteenth Doctor, joined by new companion Ruby Sunday.
Doctor Who Still Hasn’t Solved Another Big Bi-Generation Issue
David Tennant’s Fourteenth Doctor still exists within the show’s continuity
Even though Fifteen ’s admission price that bismuth - propagation is n’t something he ’s in a hastiness to double , there is still the lingering issuance ofDavid Tennant ’s Fourteenth Doctor still existing inDoctor Who . Although " The Giggle " showed Fourteen living an ordinary , domesticated existence with the Noble crime syndicate , it ’s still difficult to conceive that he ’d be contented with that lifespan on a long - terminal figure basis . At his core , Fourteen is still the Dr. , and yet it seems unlikely he ’ll return to the show to attend to Ncuti Gatwa ’s Fifteenth Doctor if Earth becomes threatened .
The Disney earned run average of Doctor Who has resulted in a confusing numbering conventionalism that begins with Ncuti Gatwa ’s first season as the Fifteenth Doctor .
Showrunner Russell T Davies has made it clear on several occasions thatDavid Tennant ’s clock time on the show is essentially over , with the future ofDoctor Whobeing entrusted to Ncuti Gatwa . While this is certainly the correct ethos , it ’s very distracting having a separate version of the Doctor survive in the present day who could conceivably return at any metre . It ’s even more perplexing when it ’s believe that Fourteen still has a transonic screwdriver , as well as a fully serve TARDIS . However , only time will tell whether Fourteen ’s on-going presence will negatively bear upon the future ofDoctor Who .
