I'll be honest in saying that I really don't know what to do to explain. I didn't go more into Jack's history because she's...Jack the Ripper. Who is pretty famous, so I assumed I didn't have to really expand on that. I could, of course, but I didn't think to.

She has a full personality and a backstory given in both her introduction story and the other chapter she appears in the end of. The novels have several chapters out already, but with such a big cast it's kind of hard to include everyone in a timely manner lmao.

If you want me to wait until she appears more, then that's fine! But I really can't figure out how to elaborate or explain further.
