I get Lae'zel and Shadowheart being at each others throats, it's a bit awkward and clunky with so few party members and with Shadowheart and Lae'zel being the only female characters but that should lessen when more characters are added. I think she's being consistent here, she's already suspicious of Lae'zel even in the ship and Lae'zel abandoning the party wouldn't have helped her opinion.
There are other points where Shadowheart seems inconsistent with her new and previous lines. Old Shadowheart would have insisted she was having a great time in the chamber and been furious if your character said they would free her and then freed her.
