I agree with you, I think Shaxs can do better. But I also think that maybe Shaxs used to be like Dr. T’Ana and feels some empathy for her. I’ll admit I was a bit kooky before I met my spouse, she recognized that my lashing out was a product of my environment and life experience and offered me a different perspective. She only knew that because she used to lash out for the same reasons and did many years of therapeutic work to get her back on track. So when she saw me hurting in the same ways, she offered me the roadmap she used and I’m a lot better for it. Maybe Shaxs feels this same way about Dr. T’Ana. He sees she’s struggling and indulges her because he loves her, but is also slowly chipping away at the hurt that they share.
