LOL! I wouldn't be surprised if Snape is jealous of Remus, and not just because Remus is able to control his classroom without scaring the wits out of them. Both of them have suffered, both had difficult childhoods, both are outsides. Snape is who Remus could have become if he had let anger, resentment, and bitterness eat at him. They're two sides of the same coin -- hence my love of the pairing.
