Now was the moment of decision making. Stay behind the tree and fail, while saving herself the trouble of breaking anything major and oh, maybe dying, or set the acromantula in a different direction and make a mad dash for the other side of the ravine. The crackling of the leaves told her she didn't have long to make this decision. Um um um....

Peering around the tree she spotted the spider moving closer, like it was trying to sniff her out which was weird because spiders didn't have noses...did they?

Guess who wouldn't be sticking around to find out? "Stupefy!" Lex didn't stop to see if it worked, on the off chance it did, she only had a little time before that spell wore on when you considered it's massive size. Perhaps she should have used the body binding curse? That would have given her more time but her brain wasn't doing that functioning well thing, she was lucky she remembered anything at all.

As she ran through the maze of trees and bushes and low hanging branches, the Gryffindor stuck a hand before her trying to avoid most of the damage as she went. No looking back, except brief glances to check she wasn't still being followed, maybe her spell worked! Or maybe the giant spider found someone else. Better them than her.
