“ There would be times in the years to come when he ( Murphy ) would accompany me back and forth between the two worlds I'd come to know. Other times, Yipes would venture out over the water, and even Matilda came along once. There were loads of clothes and seeds and jars of honey and other such things cramping our space, and children of every age moving between the pillars and The Land of Elyon. And always, always, there was Marco at the pedals, helping guide the way across the Lonely Sea. I have yet to venture off the course that was set for me by Sir Alistair Wakefield, but I see certain things on the old maps that make me curious. Are there other places to explore, somewhere in the immeasurable reaches of the Lonely Sea? Maybe my own children or their children will find these strange spots on the map. My way is set an in stone, and I don't feel the need to veer off any longer. It has taken many days of searching and fighting, but in the end I have found what I was looking for. I have found my way home. ”
