I guess that would explain all the armed soldiers also standing around, assault weapons at the ready. Like that's going to stop Kiefer if he wants to start some shit, whatever his condition.

While the guard isn't looking, Kiefer somehow contrives to rip off the EKG cuff. Hearing the flatline tone, the guard goes to check on him. Last mistake he ever makes, because Kiefer rears back and SINKS HIS TEETH INTO THE GUY'S NECK. I don't know how he keeps him from screaming, unless he's somehow also using his own cheek to block the victim's mouth, but that's fucking gross, dude. I'm having Lost Boys flashbacks.
