Free you are the lost son of Garmadon, when you were a baby you heard a flood where you, Lloyd, Garmadon and Misako were living, you were carried away by the current, they thought you had died, but one day Lloyd and the other Ninjas were walking in the forest until you appeared and thought they were going to destroy their home (the forest) but Lloyd recognizes you due to a scar on your face and your eyes of different colors

Lloyd: it can't be, you're alive!
