With apologies for derailing the thread . . .
In the quote Elegast posted from Fool Moon - Do we know whose blood that was that Justin was trying to force down Harry's throat?
Not really. I don't think we are entirely certain that that particular memory of Harry's represented what actually happened that well. It had a nightmarish quality when I read it. Harry could be remembering exaggerations.
Went back and checked: Ch.30 of GS gives us a different perspective, and none of the more colorful descriptions from Elegast's excerpt are mentioned.
