Knew I was forgetting something for Wrath. I updated her classes for her final year. For NEWT level classes she's taking the following:
Charms
DaDa
Ancient Runes
Herbology
Potions
Sisse Thompsett I think so too, we can has out how well they get along in DM or here, or just thread them and work it out that way
Wrath likely be friendly and kind towards Kitty, though they may not get too much opportunity to get to know each other. Wrath is going to be pretty focused on her studies.
