Edmund Hillary was a part of a team of men present at a base camp on Mount Everest in 1953. He was confused when the Fifteenth Doctor unexpectedly arrived in their tent, offering a ham and cheese toastie and a pumpkin latté. The Doctor, however, immediately departed upon seeing their confusion.
Shortly following this, the Doctor reappeared, this time stealing rope and a grappling hook. He asked him what he was doing, why he was taking the equipment, to which he replied simply that it was there and again vanished. Sometime later, he and his assistant Tenzing Norgay observed the Christmas star together. Tenzing asked him if he thought the weather would hold, to which he replied that it of course would, that it was in the stars.
