History Headscratchers / DoctorWho2016CSTheReturnOfDoctorMysterio

* So it turns out there's been a guy with powers equivalent to Franchise/{{Superman}} living on Earth for all these years... Which begs the question, what the heck was the Ghost doing when the Sycorax, the Cybermen, the Daleks, the Sontarans, etc., tried to conquer Earth? You'd think some of those world domination attempts could've gone a bit differently if there was a invulnerable flying man who can lift a spaceship with one hand protecting Earth?

* Being a fan of superhero comics including Franchise/SpiderMan, wouldn't Grant know that there is already a villain named Mysterio? I understand it's a meta reference to what the show is called in some Latin American countries, but when Grant says that's what the Doctor would be called in a comic book, it feels like JustForFun/OneMarioLimit should be at play here.

** Maybe that's why The Doctor stays in England and never bothers protecting the US? The Ghost already has it covered.

*** In that particular case, presumably the Master discreetly tracked down and neutralized as many such potential challengers to his power as possible ''before'' openly taking over the Earth, e.g. figuring out Grant's identity and taking his loved ones hostage. For menaces that attacked ''en masse'' or globe-spanning effects like Atmos or the instant worldwide forest, either the sheer number of enemies meant the Ghost barely made a dent in their forces or Grant didn't have the brains to puzzle out what was behind them.

** It's not as if he'd learned that much ''about'' Harmony Shoal from their first encounter, either. He only heard the name mentioned once in "Husbands", as if it was a cult rather than an alien invasion force, and he didn't even know they were brains in stolen humanoid shells at the time. Heck, for all we know he's seen people with diagonal scars across their faces dozens of times before, passing them in the street on all sorts of planets, just like he keeps randomly running into blue people: the Doctor just never came into active conflict with them until these two Christmas specials.

** Over the course of Series 10, it's revealed that Nardole's new body is a patchwork of robotics and bodged-together secondhand body parts, like lungs the Doctor got on sale somewhere and a hand Nardole won in a card game.

** In "The Pilot", it's revealed at the beginning that the Doctor built him a new robotic body that looks like his original.

** The above would apply to some of the crises, the ones that lasted only a short period of time and were limited to the UK, but not all of them. For example, during the Year That Never Was, the entire planet was made into a dystopia for year. So why didn't the Ghost fly into the Master's fortress in the sky and defeat him? It would've been easy for a guy who can lift spaceships with his left hand.

** Given that Nardole is to be a recurring character in Series 10, and it had already been announced by Steven Moffat that his story would unfold across the season, presumably this is something left intentionally a mystery for now.

** After cutting his head out of Hydroflax's body, he could have jumped back to where Nardole's body was left, since Hydroflax never checked on it.

** They may be artificial organisms, originally created as spies and/or infiltrators by another alien species that ''did'' have manipulative appendages.

** The Doctor describes them as "peripatetic central nervous systems", which implies a greater degree of mobility than the ones sitting in the blue jars display. Possibly they only ''look'' like brains when they're sleeping, or curled up small for ease of transport. What ''look'' like the convolutions of a brain could be tendrils that can uncoil and slither around ''inside'' a host body, Colony Sarff-style. If the drones on the spacecraft are any example, their surgeons don't just do a brain transplant, they hollow out the entire "vehicle" and fill it with blue gunk, which the recipient can freely move about inside.

* As the Harmony Shoal have no limbs outside of stolen bodies, how did they first start getting put in bodies to begin with?
