Hey Ali! Aw, I'm sorry to bring you down! Thanks for taking the plunge and giving it a shot and reading all the way through--I really appreciate that and also your very kind words. ♥
I admit I wondered if I need to detail Snape's motivation more--but then I felt it would get too slow and bogged down if I delved too deeply into his interior monologues. My general thought was that sometimes there isn't a lot of contemplation undertaken for potentially life-changing acts--that not every decision is a reasoned one, even those decisions that ought to be. Severus did it because--well, he could, and he felt okay about it because he was doing everything, everything for Harry. He never questioned his own love for Harry. I wasn't sure whether Snape actually felt guilty or not--I wanted to characterize him as telling himself he doesn't, but I never figured out myself whether that's just him coaxing himself into believing it, or whether it's what he actually thinks. Sometimes I wondered how things would've played out if Harry had found out (and I envisioned various scenarios, I admit :) but I felt it was fair for no confrontation to occur here, because, I guess--that's just how it is sometimes. Ack, I am inarticulate. :D
But I hope you found some fluffy fluff!! Thanks again! ♥
