That's true, although Shadowheart isn't the trusting type. A warning from her doesn't feel all that impactful.
I didn't mean Shadowheart's warnings only. For example in one conversation Shadowheart asks Lae'zel how other gith supposed to react on outsiders (us) coming with her. And Lae'zel answers that her people will understand her need for slaves. That's not something proving her good intentions. And she is being like that all the time.
