My favorite ginny moment was the library scene when ginny gave harry the chocolates from her mum in OotP. i've always thought that it wasn't really the chocolates that caused her to seek harry out but the fact that she did notice that harry's been depressed for some time. and tho it must have been quite painful for her to talk to harry and assume that cho's been the reason for harry's depression, she chose to rise past her own pain to try and help harry. i think it's one of the most telling passages in the book of how deep and mature her affection towards harry has become. and after that, harry did feel a bit better. Yay for true love!
