if he's 1000 years old you can't expect him to care about anything. i haven't completely fleshed her out yet but i'm thinking she has always been a witch and it's something that has been in her family for generations. she knows a lot of witches are anti-vampire but she never considered them harmful as long as they lived peacefully and didn't harm other people. she downplays her power because she's not into being cocky or anything but her family is old so her "inheritance" of power is pretty big. do you want to say they've known each other a long time or just recently met/hooked up?
