By blood debt, I would one day come to Alister's home underground and bring him to the world above, show him how to survive and be better than the best. Teach him how the world worked. Show him the best way of killing an Infected beast. And after all that? He would learn the truth." He wasn't hiding something per se, more like he seemed to be guilty of something unspoken. Something he would rather not say - but at this rate he probably wouldn't lie to Tesuto if the samurai pressed him.
