That depends if she can survive being shoved off the Ship.
OP I think barely anyone likes Lae'zael.
You can just kill her when she threatens you from her cage. Like seriously, all she had to do was say please. Why would I help her over the two much nicer tieflings? She's a gith with a tadpole, just put her down; that's what she would want to do to anyone else anyway.
