You are not alone. I had the same intense feelings/worries when I read it. Harry tearing the linen off the bed, being so jealous of Bill, etc. made him a loose cannon in my mind. And it's all good. It is a dark story. How can their involvement not be? I loved lonely!Snape wanting Harry in all sorts of ways, then having the tables turned as he GOT Harry in a big way. Ann and I discussed alternate endings and one of my fears for Snape would have been what if he did leave? Would Harry leak their relationship and get Sev in trouble? Would Harry take that hurt and use it as life experience with which to become a great writer? She said she was going to end it darker, originally. I think if we poke her enough with a sharp, digital finger she may be enticed to break our hearts and write an alternate ending. Do it Ann!!!!! Puhleeeze... As much as I love these guys, I wouldn't mind seeing them get put through the wringer. Maybe someday when you have nothing else on your plate. Oooh! Can't you just see Harry stalking Bill in a jealous rage? Or picking off the Weasleys next door as a message to Snape? He could start with Ginny. We hate her anyway, lol. Do it!
