One upon a time, Princess Kate was building a very tall block tower.
Sir Sam wanted to help.
Like the loving big sister she is, Princess Kate started teaching Sir Sam about block tower architecture.
Princess Kate and Sir Sam were having a wonderful time and there was peace and happiness in the kingdom.
Until the accident which displeased Princess Kate...
...and saddened Sir Sam.
But once again, like the loving sister she is, Princess Kate gave Sir Sam a hug and a kiss and told him, "We will build another tower."
And once again, there was peace and happiness in all the land.
The end.
