To lessen the apparently enormous burden of being extremely wealthy by birthright and having to raise a single child, Douglas' parents, Frederic and Daisy, brought Douglas' private nurse, Elizabeth Burns, onto the Titanic with them to take care of him during their voyage. Upon feeling the shock of the impact with the iceberg and hearing the sound of the engines grinding, Frederic and Daisy went to find out what had happened. The ship was already tilting by the time they did.
"Quick, stuff some poor people onto the other side!"
Young Douglas had totally slept through the collision, and Burns had to briefly wake him to take him to the lifeboat, at which point he fell asleep again. All she told him was that they were going to "see the stars," and clearly Douglas bought it, because he was snoring away through the night, not waking until morning, and then only to comment, "Look at the beautiful North Pole with no Santa Claus on it!"
The family made it back alive, and many years later, a distant relative discovered a book that had been written for Douglas by his mother that was a recounting of the sinking through the eyes of his stuffed polar bear, imaginatively named Polar, who had been with him throughout the entire ordeal. The book was published in 1994 to much critical and commercial success, probably adding to Douglas' despair that even his damn teddy bear got to see the Titanic sink while he couldn't keep his damned eyes open.
But years of therapy could not make the bear forget what he had seen.
