Tone:
I highly doubt that MWPP just 'figured out' that they should sneak into 
the Sly common room to look into Snape's potion's book.  It's morel 
likely Snape used it or told it to someone, whoever they may be, and it 
spread like gossip always does around the entire campus.  Maybe Snape 
added the nonverbal note later, once he saw someone else do it, to slow 
the damage.  ALSO, unless Lupin intended to lie to Harry, he claimed 
the spell had been around for forever.  Lupin trusts Harry and vice 
versa, why would he lie here?
