[That sure is a side-stepped question, and while Ren knows better than to pursue the subject blatantly, it's way too weird and interesting an aside to abandon entirely. Especially if apparently this guy is happy to resort to grave-robbing to get them (because he'd rather not think too hard about the alternative there).]

That doesn't tell me why they're so helpful, though... [There is an immense pout in Ren's tone saying that, most of which also makes it to his face.] You can't just talk all about why things are useful and prized and cool and not say why, that's bad storytelling.

[He waves a finger as if chiding him for it.]
