LB is actually wild for having the darkling place a collar on alina framing him as her oppressor while mal is out there shaming and resenting her for being anything other then the version of her he loves - weak, without a support system and entirely depended on him.

the darkling is literally the one to has to force her powers out of her because she has been repressing and rejecting a core part of herself for her entire life. mind you, rejecting her identity is making her physically ill and weak. and why has she been repressing her powers?? for who? oh right - mal.
