Louise just can't catch a break, seems like EK really have it in for her, there's just no option of somewhat earnest and amicable relationship developing between her and Lena. I feel like that master-slave route is just bad, taking advantage of a person who clearly have severe attachment issues and fear of abandonment, which should be obvious to anyone with at least more than one firing neuron in their brain, but it's not acknowledged in any way by anybody. Changing Stan in his "learning how to talk to women" arc gets pretty fairly assessed by Lena about his insecurities, but for Louise it's just dismissal and branding her as a "bad" person that uses other people for her own gain (so going by that logic it's okay to use her in return).
