True, but maturity for her culture means killing a member of an incredibly secretive other race spread out across the muktiverse. Not an opportunity I imagine appears often.
Also a minor thing, but it's strange we don't get to hear most of the companions talk about their abductions. Was it clear lae'zel was with the githyanki attacking the nautiloid? We don't get to hear where Gale or Wyll were taken from either, and it's fuzzy with Shadowheart.
