*Wesley says nothing, just sets his jaw and utters a grunt as he drives one of the teeth into the side of the cliff. He tests its strength, then mutters to Snape that he'll start down and let him know how much footing there is.* Have you ever been mountain climbing? *he asks breezily, as if trying to downplay the tension. But as Wes is lowering himself over the side of the cliff (exhibiting far more strength than he looks to possess), suddenly his hand appears to Snape to deliberately LET GO of the tooth, and Wesley plummets with a cry of surprise which turns to pain as he ricochets off the rocky cliff.
