Text: Jon caught a glimpse of the ruined twisted leg of one of the fallen riders and his throat sprayed from San'doro's wide cut.
Entailment: Jon saw the mangled leg of the rider he had been with moments ago, and saw blood spurt from his throat, cut by San'doro.
Contradiction: Jon didn't think twice about what was going on, and decided to walk right by a large rock, where the rider was being treated for a bruised elbow.
