They see Constance reading and drinking tea, unbothered really.

Constance looks up and realized they were back she sets down her tea and says-

Constance: so how was it?
Amelia: how are you alive???
Imogen: omg Constance that was horrible!
Constance: ya I know -she gets up and walks out the room to go teach her class leaving the witches with a lot of questions-

She walks in her class "good morning girls", "good morning miss hardbroom".

Constance: Ethel, take these papers and pass them out to everyone. It's the test you were meant to take a couple days ago. You have one hour, go.

She sits at her desk and reads her book but instead of reading she just thinks "how did Agatha find my file?", " I hope Amelia and Imogen don't think I'm a monster for what I am." -the timer rings- Alright girls pens down. -she gets up and collects the papers-

imogen runs in -

Imogen: CONSTANCE MISS BROOMHEAD IS HERE AND SHES LOOKING FOR YOU!

Constance: WHAT?!

-Constance sets the paper down and runs out to the courtyard, and sure enough miss broomhead was screeching at miss cackle and she was just taking it-

Miss broomhead: WHERE IS SHE?!
Constance: right here, what do you need?
Miss broomhead: you need to come with me, Cristina wants to see you.
Constance: who?
Miss broomhead: JUST COME WITH ME!
Constance: over my dead body!
Miss broomhead: -she pulls something out of her pocket which was revealed to be a small blade- YOU WILL COME WITH ME!

Constance: no,no I won't-she pulls out a small dagger from her hair , which made her hair come undone reveling her curly hair-

Miss broomhead throws the blade at her head which Constance caught and to remain professional she put them in her pocket not wishing to attack back.

Constance: that was extremely unprofessional miss broomhead.
Miss broomhead: AGHHHH -she flys off out of rage-

Constance: let's go inside shall we?
