 CHAR: When Jack is captured again and tortured, he was stabbed in a  nerve, they poured a stinging liquid on it, and stabbed him in the  back with a long but a bit thick, needle. But in the next episode,  he changed his shirt and was trying to stop someone with a bomb, he  was perfectly fine when running after him and when he hoisted  himself up with two poles to kick him. it is obvious, that  considering this takes place over twenty four hours, he couldnt  have healed in and hour from all the torture.
