Just like when he was 5 he waited and then killed. I think he was awake unless dopped up on those hospital meds, he was biding his time and waiting for that chance to escape.
OH, at first Im like, What the hell are 당신 talking about. He wasnt sleeping for ten yrs. He was in a room not speaking staring at a 벽 for 15 yrs. Oh after he returned to Haddonfield on 할로윈 1978. Yes, Dr. Loomis Torched him and part of himself in the operating room with a lighter and oxygen tanks. Then of course since a state asylum didnt cut it. He was moved to a Federal Hospital. Where he was in a coma. Loomis survived with scars. And Michael well, 당신 cant really kill him- albeit all the stupid sequels/remakes. The only ones I like are the Original 78 and I do like the 할로윈 2 in the Hospital. Beyond that not really.
