Later on, they befriended a local boy called Jack, who lived a similarly unhappy life with his grandpa on the opposite side of a nearby lake. But Jack's got a secret. He knows a island in the middle of the lake, where they can all escape and live happily. So together, they hatched a plan to escape and start a new life.

* BigBrotherInstinct: One of a few reasons Mike wanted to run away is because he wants his sister to get a good life rather then being servants of their aunt and uncle. Later Jack is also this, [[spoiler:going to the mainland even after he almost got caught, just so his adoptive brother and sisters got a special Christmas presents]]
