When the "Lost" producers were developing the character of Walt, they intended for him to display supernatural powers by summoning animals—in the episode "Special", it is suggested that Walt is able both to cause a bird to fly into a window and make a polar bear attack him through telepathy. This is also alluded to in "Live Together, Die Alone", when Ben describes Walt as being "more than Others could handle". Kelley himself was also under the impression that his character possessed "magic powers", but after he had aged significantly enough for him to look no longer ten years old, the writers' plans were changed, and Walt was written out at the end of season two.
