Jack stopped. He heard something. It was a scream. Who made it, he did not know. He looked in it's direction. All his instincts told him one thing, "GET THE FUCK OUT OF THERE!!!" But he stayed. He knew whatever it was that caused the scream was now dead, and whatever killed it was gunning for Manus and Kree next. Suddenly, without any warning, he made a mad dash in the direction the scream came from. He was afraid, but he was even more afraid of losing Manus.
