Complete story — includes the ending

Charlie's brother and band member Liam uses heroin, his unstable nature pressing Charlie into starting. Several years later, he encourages Charlie to stay with him in Sydney and get sober, but he refuses and leaves for Los Angeles. In the present, Sayid attempts to triangulate the French signal, but is attacked before he can corner it. Suffering from withdrawal, Charlie begs Locke for his drugs, who says he will return them if asked three times. He shouts at Jack and causes a cave-in. Charlie follows a moth to an opening that he digs his way out of. He asks Locke a third time for the drugs, but instead burns them as he starts to recover from his illness.
