Hmm, now that's a bit different Snape, even from canon. He seems to have grown weary of serving both his masters and appears to consider helping Harry to be a better approach to resolving matters. It's obvious he put the best possible spin on matters, but that's not -that- unusual a behavior for anyone. I have to wonder if Severus is going to shade his reports to his masters to aid and abet Harry's delaing with the situation? Not because he likes Harry but because Harry represents an alternative he dislikes less than either of his two masters. I suspect it's going to be interesting to see what happens when the Slyterhin students try to harm Harry's friends, there may well be several spending considerable time with Madame Pomfrey.
