Final answer:
Jammer hitting Nelson's foot resulted in Nelson staggering, seeking support from a rock, and collapsing due to a previous gunshot wound to his hand.
Step-by-step explanation:
When Jammer hit Nelson's foot, the impact caused Nelson to stagger to his feet and struggle to maintain his balance. He then moved toward a large, leaning rock that rested on a small base, perhaps seeking support for his injured form. Desperately, Nelson placed his hand on the rock, the same hand that had sustained a gunshot wound, and as he did so, Jane observed the blood dripping from the torn flesh of his wound. Ultimately, Nelson's strength gave out, and he collapsed to the ground.
