I imagine it's rare for Dottie to find anyone who could give her a good fight. Look at the way she smashes that table against Jack Thompson's throat. (Poor Jack. He goes to uncuff her, just like Peggy did, and Dottie is so unimpressed.)

So when she meets Peggy - and Peggy is also a woman, which makes her even rarer - well, naturally it's intriguing.
