Alot of fanfiction I have read that features D/G as a ship also has Blaise Zabini as Dracos either cousin, friend or ally. whatever he is Dracos friend and through that Ginnys or he is just there. either way It seems that these three characters are often stuck as a trio. (not that I'm complaining)
As much as I like Dracos character he has that ego...that need to feel superior. and Ginny has as I see it the will and determination to be a rebel not just be classified as another weasley if you toss in Blaise, a character who as I see as liking to be in the shadows but very cunning like a snake waiting to strike, combine all three you get a great trio.
I love fics that feature these three as main characters but I was wonering if anyone else has any comments on this.
