Which, Kylo attempts to remind himself, is what he'd wanted proven. Ronan's distaste for giving up the names of customers and suppliers is supposed to feel like a protection rather than a disappointment, and he already has what he came for. The capsules. He has more than enough. There's no reason for him to waste any more time on Ronan Lynch.

So why is everything screaming at him not to let him retreat back into his sanctuary?

"No," Kylo agrees. "Wise of you. And I know where to find you, should I require anything else."

He'll let him go. He'll let Ronan take his jumbled nerves back into the locker room, then turn and leave. He has no reason to do anything else.
