I'm wondering if Blake will have known Tukson or whether what happens come to her attention (maybe Mercury or Emerald try taunting her with the knowledge that she isn't the first cat-faunus they've killed). So, yes, it might ultimately turn into a character development point for her.

If Emerald switches sides, I can see Blake challenging her and asking her if she ever regrets being a killer. Her reply might be: "No. I had things like that burnt out of me a long time ago. Sometimes figuratively... sometimes literally."
