Wow, that was good.  Maybe you'll get some extra credit from Lupin after he gets back to normal!  He'll be all right after the full moon is gone.  So, your next task is to get Aragog under control.  Hagrid says that they are just being themselves, but to be honest Aragog has gotten a bit out of control.  We just need you to put him in a trance for now and the teachers will deal with him later.  Beware of those pinchers!
