Rue is odd. She’s always been odd. There’s just something mildly unsettling about her. It could be her eyes, that startling shade of green that almost seems to glow. Or the way she moves, which is slow and methodical until it isn’t. Maybe it’s how she smells of strange plants. The eyes that follow her in the bush.
She seems normal enough. She’ll smile and offer you tea. Maybe some cake. But the tea has a strange aftertaste, something sweet and sour that lingers on your tongue. You feel calmer once you leave her bungalow. You don’t get the sense she would ever hurt you, but she it seems unwise to anger her.
In truth this is because Rue has some Fae in her. But it also reflects in her personality. She is very cordial to everyone she meets, she’ll do you a favour in a heartbeat. But the favour always comes with an expectation of something in return and you won’t know what it is until she asks.
Rue also has a tendency to be spiteful, often over seemingly petty things. Snap a twig off an old gum tree, find spider silk thrown around your bedroom. Swear in the presence of a magical creature, have your cornflakes turn to bitter nettles. Her revenges seem almost as odd as the perceived slight. No student will ever come to serious harm and she is far more likely to give them a detention. However misconduct around the Neighbours will earn you a harsh reprimand in the form of a karmic backlash or nasty punishment. It may even be painful, depending on the slight. But Rue does this to protect the students. She exacts revenge in place of the Neighbours who would have inflicted far worse. Students who fail to learn proper conduct must either say nothing, or leave her classroom.
Her class is Herbology, but she calls upon the Fae to help and many of them visit her bungalow for a potion, tonic or other magical item. Learning to interact with them is a survival skill important to any witch or wizard, so she conducts classes outside her bungalow.
Students are rarely invited inside as there is a lot of delicate magic going on in there.
Rue loves children in her own way. She’ll protect them against all harm to the best of her ability, no matter how horrible they are. Children are children and they are still learning. But there are limits to her influence over the Fae only goes so far. Her kinship with them means that she can get away with things most mortals would be killed for, but there are some lines even she cannot cross.
Just because she loves children doesn’t mean she’s any good at interacting with them. Obviously she can easily frighten a lot of the younger ones. She doesn’t expect to have many little ones with her in her first year.
She is also careful of overstepping her bounds in case the Ministry of Magic ups her threat level. She despises them for their prejudice against non-humans and finds it very hard to hide her disdain.
When she is angry or dislikes someone she very rarely says so directly, hiding behind passive aggression and double entendre. She will never fail to give you a friendly smile, though that in itself can be a little creepy.
