Branwen nodded slowly as she listened. "It makes sense, if your Patronus is a reflection of who you are, and you Animagus form is as well, that thy would be similar." She smiled. "So it's a good thing then."
Branwen pushed her book off to the side, repositioning herself slightly, absorbing Lucy's words. She nodded firmly, twice. "McGonagall's clever, and for all she doesn't believe in Divination, it was almost like she predicted this, if she was training you in something top secret like that."
She paused. "I know she'd want us to do something," she said with conviction, but lowering her voice. She didn't even think twice about telling - Lucy would probably find out for herself soon enough, at any rate. "Because - and I know you won't tell - in the classes I'm currently taking" - she made a face - "McGonagall is teaching us, and when the Ministry isn't watching, she'll teach us wandless magic."
