*Snape quickly weighs his options; run towards the slightly closer hollowed chest cavity, or the high ground of the monstrous corpse that's a little farther away. He doesn't like the thought of being trapped in the cavity if they should be outnumbered, and the smell of being inside a rotting corpse...was there ever a choice? He gritted his teeth and ran to the bloated corpse and started climbing, keeping part of his attention focused on Wesley, in case he needed help.*

Run, Wesley! I'm climbing up now!
