Jack's kneeling next to you, being cautious as he examines your condition. His eyes watching your expressions while his hand rests on your chest over your heart, ready to pierce through your chest to your heart if he finds it necessary to kill you.

"Hey kid... Come on, wake up. I know you're not down for the count yet, better not think of dying on me if you're still sane."

Jack's hoping you won't succumb to frenzy if you're still alive, last thing he needs is to deal with someone who becomes a Lost from their Bloodlust.
