The fundamental issue here is assuming Fred and Angelina were really into each other. All we know is that they went to the Yule Ball together, which means nothing, because Harry and Padma went together, and they didn't often speak except about school things.
I found it weird when I first read that Geogre marries Angelina but now I think it's kind of cute that they bonded over Fred's death but I'm still in for Angelina/Fred
I can see JK Rowling has paired some pairings that fans didn't expect like Draco/Astoria (who I can picture her as a Ravenclaw), Hannah/Neville and Luna and this Rolf dude . For other pairings that she may talk about in the future, I would like to see Seamus with maybe Susan Bones and Oliver Wood with maybe Percy's ex girlfriend in Ravenclaw who I can't remember the name.
i think its alright, i dont think Fred and Angelina were all that serious, just because they went to the Yule Ball together. i really like her close friendship/relationship with the twins. i actually wrote a bit of George/Angelina a while ago. This pairings pretty alright with me.
I really don't like it.... I feel that the twins are very different from each other. So I am still not okay with the pairing. I did like George and Verity shipping who worked with the twins at the shop I think there are a couple of fanart out there. And for some reason I always pictured Fred marrying a muggle... I don't know why maybe because he was the one who'd go pick the muggle girls with magic
I first found it a little odd because Angelina went to the Yule Ball together, but the way he asked her out made it seemed like they were going as friends so I guess I'm pretty neutral on this subject.
But, and I know I'm a little off topic, I am a little mad that Fred died. He was a great character and the twins had such a special bond.
