Meanwhile, Kylo had never considered that he might be thanked for something so obvious. One confused eyebrow raises in reply.

Snoke wouldn't have made that same promise, Kylo is sure, but even he wouldn't have wasted someone with skills like Rokuro has. He had put Kylo through plenty of dangerous experiences early on, in training, but especially given that response, it's clear that Rokuro doesn't need to learn the lessons of knowing his own limits and not expecting a safety net.

"Death would be a waste of your abilities." Had his prior commanders not realised that? Or were his powers so common wherever he came from that it simply didn't matter?
