The Curator was often visited by Clara Oswald, although he pretended not to remember her.ĭuring one of his many visits to Alistair Gordon Lethbridge-Stewart, the Curator asked him what the most important quality in a UNIT commander was, and he responded with the answer of "good handwriting". He and Ohila were good friends by this point, and she told him she had actually given him dry ice and lemonade and went on to explain that the dark nature of the Doctor had always been inside of him and she just needed him to believe it had come from somewhere else while he was the War Doctor.

Many years after the Eighth Doctor had regenerated on Karn, in circumstances "too scandalous to relate" to others, the Curator asked Ohila what had been in his regeneration potion that supposedly contained the Elixir of Life. ( TV: Kill the Moon) Rassilon would later state his own uncertainty to the number of regenerations the Doctor had been granted, ( TV: Hell Bent) with the Master and Missy also considering their own uncertainty when debating whether to throw the Twelfth Doctor from a roof, believing they "could have been up and down the stairs all night". When Captain Lundvik threatened to shoot him, the Twelfth Doctor speculated that he would "keep on regenerating forever" if he was executed.

When the Eleventh Doctor's timeline became distorted, the Curator was seen as one of his future incarnations, at the end of his lifespan.

When encountering the " Vortex Butterfly", the Tenth Doctor was cryptically told that he would not be "limited" to "thirteen lives".
