Found on a table on the front balcony of the overlook cabin.
Anya: Kelly, I got your message from the dead drop! I've been waiting up here for you but I'm starting to get kinda worried. You're probably just hiding in the hedges from those robots, but I'm going to go look around for you just in case. If you get this, just stay here! I don't think it's true, but we should probably try to move on from here if the folks here are taking notice. you are now! So ... bye?
