Cass doesn't seem to like this idea. It seems to her that if she simply places the Second Clue in it's rightful place and leaves this place completely unattended. Knowing Raven he could know full well where the Second Clue was and just jump willy nilly to the Forbidden forest just to get another adventure out of the way.
But no, the better thing to do before Raven got himself ravaged by a rampant cerberus (she's heard such a thing) was to send warning posts so he didn't get himself hurt.
On the outskirts of the forest near the main opening and a great deal less nettles, Cass sticks the little pieces of parchment to every other tree. He'd notice it if and when he's keeping his eyes sharp for them, he'll approach them.
The note says
Sucker.
(With a fancy elaborate drawing of a frog sticking it's tongue out)
Silly Raven.
She skips out to get the actual clue put up.
((OOC: it seems to be that the WW was the actual hiding place of the second clue, but it looks like Raven has better ideas))
