When Alec is talking to the girl in the hospital bed - around the 3:25 mark - she claims to have "...a couple sixes..." (insinuating 6th degree burns). 6th degree burns - where everything is burned off and the bones are charred - are generally discovered at autopsy. 6th degree burns are almost always fatal. If death does not occur, amputation will be required. The girl in the hospital bed does not have any amputated limbs.
