This was it! Moment of truth, either the Whomping Willow had lured Oakey into the biggest false sense of security of his life, or the Tree was going to allow him to cut from it's bark. He wondered while he slowly moved his wand to the extended limb of the Willow if it enjoyed the Chant. Did he make it feel even more important than usual?
"Diffindo." Oakey quickly barked and sliced off a piece of the Whomping Willows bark. Oakey backed up quicker and quicker until and eventually stopped. He was holding a small bit of the Whomping Willow in his hand, if the Tree was going to squash him, it'd have done it the moment Oakey sliced the piece right off.
-----------DADA OOC: Figured I'd give an Explanation of What Happened to Oakey-------------- Slow! Right got it! So Off Oakey went, while everyone started to Jog, Oakey went along with them, slow first, slow first...were they just going to jog around the Willow or move around the Grounds? Oakey figured they'd move around the Grounds so. He broke off from the group expecting them to do the same. Off Oakey jogged into the distance towards the Pathways, while everyone else ran around the tree.
They'll catch up to him eventually.
