Walker took a giant leap backwards after watching Zayn stab himself in the guts. He was shocked by the man's action, and his instincts were telling him to back away for the moment. 'why would he fatally wound himself in a battle where he was at clear disadvantage?' He asked himself. It didn't make sense, unless he had a death wish. Something was definitely up, 'maybe he needs to mortally injure himself in order to activate his gift. If that's the case, then I shouldn't let him finish whatever he's doing' he hypothesized before launching forward at Zayn.
If the man wanted to die so badly, then he'll gladly help him do so. 'What's this smell, fragrance?' He wondered before bringing his blade down at Zayn who promptly defended the attack. Walker leapt away swiftly once more. 'was that the scent of his blood?' He wondered. Something was up with this psychopath, he could feel it but he couldn't put his finger on it.
