i suppose it would depend on the circle she thieves from or if she'd ever partnered with destrian on a job she sent him on? her being a half-elf would definitely be cause for calpurnia to be hesitant, but then figure it could be an angle to exploit. never hurts to have someone you could potentially send into enemy territory, if roslyse can pass for full-elf or close enough. if that doesn't work, we can totally wait for them to cross paths in-game and work from there!
