I'm not sure. I don't know if it's driven by her being a girl or her being a "victim" or both. I think Paul has White Knight Syndrome.
I think a lot of it seems driven by what happened to Alvarez in the beginning. He was beating himself up over not knowing things about Alvarez even though he sat across from her for 2(?) years. Things he felt he should have known. It seems natural to me that he would take more of an interest in Rebecca, personally as well as professionally.
Serial killers, serial rapists, they tend to target women and children, and so that's what we'll see.
Yes. Absolutely. A television show realistically portraying the mysogyny that exists in society, and the charcters maybe even using it to their advantage in going after the bad guys, doesn't equate to promoting it or excusing it, in my book.
