Is Remus Lupin an Occlumens/Legilimens?

To prepare myself whenever a new Harry Potter book draws close to publication, I reread the entire series from start to finish. There are two reasons I do this. The first and most obvious is to refresh my memory on what has happened and what questions we are left with at the end. The second is to look for clues, hints, and little tidbits that I may have missed the first time around.

By going from one book to the next without stopping, this also allows me to get a clearer picture of the characters' (particularly Harry's) states of mind. Doing this meant that I was not nearly as annoyed at Harry's temper in OotP as many fans. We had four years to digest the stress of the Triwizard Tournament, the death of Cedric, and the resurrection of Voldemort in between books four and five. Harry only had a month, and I think many people forgot this fact. They forgot that Harry had been under considerable stress his entire fourth year, and were thus unprepared for the anger and frustration that he expressed in OotP.

But I digress. This essay isn't about Harry or his emotions. It's about some rather interesting things surrounding a certain Professor Remus J. Lupin that, in light of Snape's explanations of Occlumency/Legilimency, have made me come to suspect that my favorite lycanthrope may be more than what he appears.

All in all, we can't be sure until the 16th. Will Harry's Occlumency lessons continue? And since Umbridge has been kicked out and Dumbledore's reputation restored, will Snape be his professor in this subject, or will it be handed over to Remus. (If he is an Occlumens/Legilimens, that is.) Part of me wants this to be so, merely so that I can have more Remus to read about, although I think Harry deserves a good teacher for a change. (Not that Snape lacks the abilities or the intelligence. But he's such an ass.)
