Snape is uncomfortable expressing positive emotions (and I'm not sure if he feels very many positive emotions, either), but he does try to take positive actions. A lot of what he does goes right over Harry's head.

Lupin loves Harry, but is finding it harder to like him, if that makes sense. He also feels can't allow himself to show it, because that could (in his opinion) prevent Harry from accepting Snape's new role in his life. If he jumps in whenever Harry has a problem, how will Harry ever learn to rely on Snape? It even seems to be working. Ever since Lupin took a giant step back from Harry, Harry has been having more meaningful conversations with Snape and going to Snape when he has problems.

Harry definitely needs someone in his life to confide in, trust, and get comfort from. Snape doesn't want to do it, Lupin wants Snape to do it because he doesn't think he will be around for very long, the Weasleys are busy saving their own kids (and the extra ones they have taken in), and McGonagall is facing running Hogwarts by herself. It's a tough situation. Hey, maybe Harry could get adopted by Bill or Charlie, who don't have as much going on in their lives as the other adults? But then it would be a whole different story. :-)

Harry will be stumped by Hermione's gift as well, for a while. She tried to be too sneaky and clever. I wanted to see if any readers would figure it out before it's revealed. In the next chapter it will be revealed what Harry thinks she sent.

Thanks for reviewing!
