I am on the best team EVER! Look at this fic! DUDE!
I loved your use of flashbacks and the way you eventually had to break Harry and bring him down to the bottom before things could start looking up. so sad, but it totally worked. I also loved Harry's threat, Severus' Muggle quotes, the use of the organized/disorganized theory, Albus' portrait, and THE CASTLE!
(I may also have thought that Harry losing it and taking Severus against the settee was so very wrong/sexy/uncomfortable/hot/wow.)
I am just envisioning the sit-down Harry is going to have with his friends now, and the look on Hermione and Minerva's faces when they find out who he's really been 'drinking' with. :D
