Is it fitting when a show called "Lost" loses an entire plotline? In the early days of "Lost," young Walt was a major player. He was "special" and displayed eerie psychic abilities that had a tendency to kill bystanders... including his own mom. But then he left the island and we never found out exactly how his eerie powers worked. Today, Kelley is 19, and stars on the TeenNick series, "Gigantic."
