I just realized that there is no thread for Lucy!
What do you think she looks like?
I imagine her with wavy-ish blonde hair and maybe green eyes. I think she'd basically look like her mother, who I always thought was blonde for some reason. But maybe Lucy has reddish-blonde hair, because she is a Weasley, after all.
Do you think she loves and always abides by the rules like Percy does?
Probably not. I see Lucy as bubbly and energetic, which is also how I think of her mother. But then she'd have a temper like Mrs. Weasley and Ginny.
What house would she be in?
I see her as a Gryffindor, or maybe a Ravenclaw.
