Absolutely. Most of them wouldn't even be open to the idea of letting them prove otherwise. Not that the kobold plans to try - her tribe puts up with her weirdness now, but only because she's proven that she's not going to put anyone but herself in danger, and that's a fairly fragile understanding; trying to get any of her tribemates involved could easily get her exiled, if her tribe decided they couldn't trust her any more.
