So imagine if in around 6th year, Harry brings up the fact that if he married one of the Weasleys, he would legally be a part of this family. The most reasonable answer would be Ginny, to marry Harry some day. But, what if all of them start fighting over it?
Harry: So, I was thinking.. hypothetically if I married one of you guys.. then by the law, i would techinaclly be part of this family
Everyone: ...
Fred: *swinging an arm around Harry* Well all you had to do was ask
George: *swinging his arm around Harry's other side* Who are we gonna invite?
Harry: *blushing* Uhhh thats not what i meant..
Charlie: *looking at the twins* i have access to dragons. dont test me.
Ron: if anYONES GONNA MARRY MY BEST MATE, IT WILL BE ME
Ginny: *rolling up her sleeves* IM WILLING TO FIGHT YOU FOR HIM
*ron and ginny get into a cat fight*
Mrs and Mr Weasley: *facepalm*
Harry: guys what the fuck
