Jack is on high alert as the creature disappears, but he can't afford to waste bullets shooting at nothing. He slumps against the tree behind him, finally pausing long enough to feel the blood loss. He sets his gun aside, and fishes around for a heath kit; really just a tin box with a syringe of glowing red Adam in it. He injects it quickly into his arm and breathes a huff of relief as the wounds on his shoulder close up, and his bruises fade. Alright, he can do this.

He pushes himself back to his feet and trades the gun for his trusty wrench, treading carefully as he tries to find Ivar again. His left hand is sparking with electricity, just in case.
