I kinda have a feeling that one of the Weaslys won't make it through the book. I think it might be Percy or one of the twins or both the twins. Mrs. Weasly kinda put the curse on the twins in GOF when they came back from the world cup. And Percy's been in the bad books for a while now with the family. Any of them going would bring Mrs. Weasly and the rest a lot of grief. To see Mrs. Weasly cry would bring the clouds down on a lot of us too.
