Well, there's two things that might make Rachel feel better about this: firstly, Mel's kind of supernaturally designed to be a hunter, but more importantly, you don't get very far as a thief if you can't keep an eye on a mark without making it look like you're keeping an eye on them.

She looks up at the triangle, her very specific historical and mythological knowledge failing on this count, and figures that this place looks interesting at least.

And by 'interesting' she means 'don't let teenagers go in their on their own'.

She scoots along the branch, lying on her chest as she waits to see what will happen.
