i have two harry's in my head - one is a bit darker because of his childhood - but the other, this harry, overflows with love for his children because he wants them to give all the love he never received. and so his kids are not afraid of anyone - all they know is being cherished which is why james has no fear at all!
and well, ginny - i think she's a bit spoiled (being the only girl AND the youngest kid) but with 6 brothers she must be a tomboy - one of the boys really!
