my answer to kokiri85, about Sirius' character assassination
JKR says this and this and that about Sirius, about how he is. Sometimes I wonder if she has a heart when it comes to him. But she did get the loyalty thing right though, I will grant her that.
Read it and weep.
SORRY, I could NOT get a cut to work, so here is a link to a word document. Hope that suffices.
