Everyone is wondering why capaldi’s doctor cant fly the Tardis, seriously did you even watch doctor who? Every doctor after regenerating becomes unstable often including memory loss, Paul McGann’s doctor literally forgot he was a time lord.
The Third Doctor passed out for days, waking up only to violently cuddle his shoes, and then made a wild escape on a wheelchair.
The unfortunate part is that if any of us saw Kato like that in real life, we’d need the very fainting couch she’s using. Fortunately, we know from last week that Kato has some pretty comfortable floors.
