In the very first episode,and i mean the very first episode, Jack, Kate and Charlie go off to find the cockpit of the plane. They find the pilot still alive who then gets taken and killed by the smoke monster. Pretty much crapping themselves Jack , Kate and Charlie run away. Charlie trips up and gets his foot stuck so Jack goes back to help him, meanwhile Kate is still leggin it and soon finds herself all alone. Kate counts to five, opens her eyes and Charlie is stood in front of her. She wants to know where Jack is but Charlie say he dont know. Kate and Charlie go to look for him and all of a Sudden Jack comes out of the jungle as if nothing happened. So why did Jack leave Charlie? Where did he go? I reckon the smoke monster got him right back then in S1 E1!!! Yes i am mad but funny if true.
